S-8363 Series www.ablic.com www.ablicinc.com STEP-UP, SUPER-SMALL PACKAGE, 1.2 MHz PWM / PFM SWITCHABLE SWITCHING REGULATOR Rev.2.0_02 (c) ABLIC Inc., 2010 The S-8363 Series is a CMOS step-up switching regulator which consists of a reference voltage source, an oscillation circuit, an error amplifier, a phase compensation circuit, a current limit circuit, and a start-up circuit. Due to the operation of the PWM / PFM switching control, pulses are skipped under the light load operation and the S-8363 Series prevents decrease in efficiency caused by IC's operating current. The S-8363 Series is capable of start-up from 0.9 V (IOUT = 1 mA) by the start-up circuit, and is suitable for applications which use one dry cell. The output voltage is freely settable from 1.8 V to 5.0 V by external parts. Ceramic capacitors can be used for output capacitor. Small packages SNT-6A and SOT-23-6 enable high-density mounting.

Switching control method The S-8363 Series switching regulator automatically switches between the pulse width modulation method (PWM) and pulse frequency modulation method (PFM) according to the load current. A low ripple power can be supplied by operating on PWM control for which the pulse width changes up to 88% in the range where the output load current is large. The S-8363 Series operates on PFM control when the output load current is small and the pulses are skipped according to the amount of the load current. Therefore, the oscillation circuit intermittently oscillates, reducing the self-current consumption. This prevents decrease in efficiency when the output load current is small. The ripple voltage during the PFM control is very small, so that the S-8363 Series realizes high efficiency and the low-noise power supply. The point at which PWM control switches to PFM control varies depending on the external element (inductor, diode, etc.), input voltage value, and output voltage value, and this method achieves high efficiency in the output load current of about 100 A. 8 STEP-UP, SUPER-SMALL PACKAGE, 1.2 MHz PWM/PFM SWITCHABLE SWITCHING REGULATOR Rev.2.0_02 S-8363 Series 2. Low voltage start-up 2. 1 Start-up circuit The S-8363 Series can startup from 0.9 V. When the VOUT voltage at ON / OFF = "H" does not reach the STU release voltage, the start-up circuit starts the operation and outputs the fixed duty pulse to the CONT pin. By this, the VOUT voltage starts step-up. After that, the VOUT voltage reaches the STU release voltage and the STU mode circuit is set in STU release condition, therefore, the switching control circuit starts stable operation due to the soft-start function. Simultaneously, the start-up circuit is set in disable condition, so that the S-8363 Series prevents excessive current consumption. 2. 2 Start-up mode (STU mode) circuit The STU mode circuit monitors the VOUT voltage, and switches the operation modes between start-up period and normal control period of the switching control circuit. The STU release voltage is internally fixed at 1.4 V (typ.), and has hysteresis of approx. 0.15 V. When the VOUT voltage decreases to 1.25 V (typ.) from release condition, the STU mode circuit is set in the STU detection condition, shifting to the start-up period. Several s to several ten s is taken to shift from STU release to PWM release. During this the step-up operation is not performed, therefore, the VOUT voltage may largely decrease depending on the size of load. During applying ON / OFF = "L", the STU mode circuit is set in disable condition, so that the S-8363 Series prevents excessive current consumption.

The VOUT pin also works as the power supply pin. The voltage applied on the VOUT pin when ON / OFF = "L" is VIN VD. VD is forward voltage for step-down of SD, and largely varies depending on the forward current If of SD and ambient temperature, but Vd is approx. 0.2 V to 0.5 V. When the S-8363 Series startups from 0.9 V, use a SD with specially low VD. When using CRS08 for the S-8363 Series, start-up is guaranteed when Ta = 25C and a load current of 1 mA. Satisfy the following conditions when using other SDs. Low forward voltage (VD) High switching speed Reverse withstand voltage of VOUT + spike voltage or more Rated current of IPK or more Table 7 Typical Schottky Diodes Manufacturer TOSHIBA CORPORATION ROHM Co., Ltd. Remark Name CRS02 CRS08 RB161M-20TR RB051LA-40TR RB070M-30TR RB161SS-20T2R Generally, in diodes with low forward volage VD, reverse leakage current Ir tends to increases. Especially, increase of Ir in high temperature is significant. To prevent decrease in efficiency, choose a diode with low Ir when low voltage start-up is unnecessary. 10 STEP-UP, SUPER-SMALL PACKAGE, 1.2 MHz PWM/PFM SWITCHABLE SWITCHING REGULATOR Rev.2.0_02 S-8363 Series 3. Soft-start function The S-8363 Series has the built-in soft-start circuit. When power-on (connecting ON / OFF to VIN) or after start-up at ON / OFF = "H", the output voltage (VOUT) gradually rises, suppressing rush current and overshoot of the output voltage. In the S-8363 Series, the soft-start time (tss) is from start-up to the time to reach 90% of the VOUT output voltage setting value (VOUT(S)). A reference voltage adjustment method is adopted as the soft-start method, the reference voltage gradually rises from 0 V simultaneously with start of the soft-start. The soft-start circuit has two operation modes which is selected according to the VOUT voltage at start-up. 3.1 VOUT voltage at start-up STU release voltage The soft-start starts when the reference voltage gradually rises after ON / OFF = "H".

When the VOUT voltage reaches the STU release voltage, the soft-start starts. Since the length of the start-up period largely varies depending on the input voltage, load current, external parts and ambient temperature, the soft-start time varies according to them. Perform sufficient evaluation with actual application.

Setting ON / OFF = "H" starts soft-start again. When the VOUT voltage drops and decreases more than the STU detection voltage by an overload, the soft-start circuit shifts to the start-up period. When the VOUT voltage is restored by releasing overload, the soft-start function is performed. If the VOUT voltage is not decreased less than the STU detection voltage, the soft-start function is not performed when restoration.

Power-off pin This pin stops or starts step-up operations. When the ON / OFF pin is set to the low level, the internal driver of the CONT pin is turned off and all internal circuits stop substantially reducing the current consumption. The ON / OFF pin is set up as shown in Figure 13 and is internally pulled down by using the depression transistor, so all circuits stop even if this pin is floating. Do not apply a voltage of between 0.25 V and 0.75 V to the ON / OFF pin because applying such a voltage increases the current consumption. If the ON / OFF pin is not used, connect it to the VIN pin. Table 8 CR oscillation circuit Operates Stops ON/OFF pin "H" "L" VIN Output voltage Set value VIN VD VIN ON/OFF VSS Figure 13 5. Current limit circuit A current limit circuit is built in the S-8363 Series. The current limit circuit monitors the current that flows in the Nch power MOS FET and limits current in order to prevent thermal destruction of the IC due to an overload or magnetic saturation of the inductor. When a current exceeding the current limit detection value flows in the Nch power MOS FET, the current limit circuit operates and turns off the Nch power MOS FET since the current limit detection until one clock of the oscillator ends. The Nch power MOS FET is turned on in the next clock and the current limit circuit resumes current detection operation. If the value of the current that flows in the Nch power MOS FET remains the current limit detection value or more, the current limit circuit functions again and the same operation is repeated. Once the value of the current that flows in the Nch power MOS FET is lowered up to the specified value, the normal operation status restores. The current limit detection value is fixed to 1.1 A (typ.) in the IC. However, under the condition that ON duty is small, between the detection delay time of the current limit circuit and the ON time of the Nch power MOS FET, the difference is small. Therefore, the current value which is actually limited is increased. Usually, when the difference between the VIN pin and VOUT pin is small, on duty is decreased and the limited current value is increased. 14 STEP-UP, SUPER-SMALL PACKAGE, 1.2 MHz PWM/PFM SWITCHABLE SWITCHING REGULATOR Rev.2.0_02 S-8363 Series Operation Principles The S-8363 Series is a step-up switching regulator. Figure 14 shows the basic circuit diagram. Step-up switching regulators start current supply by the input voltage (VIN) when the Nch power MOS FET is turned on and holds energy in the inductor at the same time. When the Nch power MOS FET is turned off, the CONT pin voltage is stepped up to discharge the energy held in the inductor and the current is discharged to VOUT through the diode. When the discharged current is stored in COUT, a voltage is generated, and the potential of VOUT increases until the voltage of the FB pin reaches the same potential as the internal reference voltage. For the PWM control method, the switching frequency (fOSC) is fixed and the VOUT voltage is held constant according to the ratio of the ON time and OFF time (ON duty) of the Nch power MOS FET in each period. In the PWM control method, the VOUT voltage is held constant by controlling the ON time. In the PFM control method, the Nch power MOS FET is turned on by fixed duty. When energy is discharged to VOUT once and the VOUT potential exceeds the set value, the Nch power MOS FET stays in the off status until VOUT decreases to the set value or less due to the load discharge. Time VOUT decreases to the set value or less depends on the amount of load current, so, the switching frequency varies depending on this current. L I2 SD VIN IOUT VOUT I1 CONT Nch power MOS FET FB VSS Figure 14 COUT RL Basic Circuit of Step-up Switching Regulator The ON duty in the current continuous mode can be calculated by using the equation below. Use the S-8363 Series in the range where the ON duty is less than the maximum duty. The maximum duty is 88% (typ.). ON duty = (1 VIN VOUT + VD*1 ) 100 [%] *1. VD : Forward voltage of diode 15 STEP-UP, SUPER-SMALL PACKAGE, 1.2 MHz PWM/PFM SWITCHABLE SWITCHING REGULATOR Rev.2.0_02 S-8363 Series 1. Continuous current mode The following explains the current that flows into the inductor when the step-up operation stabilizes in a certain status and IOUT is sufficiently large. When the Nch power MOS FET is turned on, current (I1) flows in the direction shown in Figure 14. The inductor current (IL) at this time gradually increases in proportion with the ON time (tON) of the Nch power MOS FET, as shown in Figure 15. Current change of inductor within tON : IL(ON) = IL max. IL min. VIN = L tON When the Nch power MOS FET is turned off, the voltage of the CONT pin is stepped up to VOUT + VD and the voltage on both ends of the inductor becomes VOUT + VD VIN. However, it is assumed here that VOUT >> VD and VD is ignored. Current change of inductor within tOFF : VOUT VIN IL(OFF) = tOFF L The input power equals the output power in an ideal situation where there is no loss by components. IIN(AV) : PIN = POUT IIN(AV) VIN = IOUT VOUT VOUT IOUT ....................... (1) IIN(AV) = V IN The current that flows in the inductor consists of a ripple current that changes due to variation over time and a direct current. From Figure 15 : IIN(AV) : IL 2 VOUT VIN = IIN(DC) + tOFF 2L VIN = IIN(DC) + tON .............. (2) 2L IIN(AV) = IIN(DC) + Above, the continuous mode is the operation mode when IIN(DC) > 0 as shown in Figure 15 and the inductor current continuously flows. While the output current (IOUT) continues to decrease, IIN(DC) reaches 0 as shown in Figure 16. This point is the critical point of the continuous mode. As shown in equations (1) and (2), the direct current component (IIN(DC)) depends on IOUT. IOUT(0) when IIN(DC) reaches 0 (critical point) : tON VIN2 IOUT(0) = 2 L VOUT When the output current decreases below IOUT(0), the current flowing in the inductor stops flowing in the tOFF period as shown in Figure 17. This is the discontinuous mode. 16 STEP-UP, SUPER-SMALL PACKAGE, 1.2 MHz PWM/PFM SWITCHABLE SWITCHING REGULATOR Rev.2.0_02 S-8363 Series IL IL max. IIN(AV) IL min.

Inductor The recommended L value of the S-8363 Series is 2.2 H. Caution When selecting an inductor, be careful about its allowable current. If a current exceeding the allowable current flows through the inductor, magnetic saturation occurs, substantially lowering the efficiency and destroying ICs due to large current. Therefore, select an inductor such that IPK does not exceed the allowable current. The following equations express IPK in the ideal statuses in the discontinuous and continuous modes : 2 IOUT (VOUT + VD*2 VIN) fOSC*1 L *2 *2 VOUT + VD (VOUT + VD VIN) VIN I IPK = *2 *1 OUT + VIN 2 (VOUT + VD ) fOSC L IPK = *1. *2. (Discontinuous mode) (Continuous mode) fOSC : oscillation frequency VD is the forward voltage of a diode. The reference value is 0.4 V. However, current exceeding the above equation flows because conditions are practically not ideal. Perform sufficient evaluation with actual application.

Diode Use an externally mounted that meets the following conditions. Low forward voltage (Schottky barrier diode or similar types) High switching speed Reverse withstand voltage of VOUT + spike voltage or more Rated current of IPK or more 3. Input capacitor (CIN) and output capacitor (COUT) To improve efficiency, an input capacitor (CIN) lowers the power supply impedance and averages the input current. Select CIN according to the impedance of the power supply used. The recommended capacitance is 1 F or more for the S-8363 Series. An output capacitor (COUT), which is used to smooth the output voltage, requires a capacitance larger than that of the step-down type because the current is intermittently supplied from the input to the output side in the step-up type. When the output voltage is low or the load current is large, enlarging an output capacitance value is required. Moreover, when the output voltage is high, connecting a 0.1 F ceramic capacitor in parallel is required. Mount near a VOUT pin as possible. The indication of an output capacitor to the setting value of VOUT voltage is shown in the table 10. Perform thorough evaluation using an actual application to set the constant when selecting parts. A ceramic capacitor can be used for both the input and output.

Output voltage setting resistors (RFB1, RFB2), capacitor for phase compensation (CFB) For the S-8363 Series, VOUT can be set to any value by using external divider resistors. Connect the divider resistors between the VOUT and VSS pins. Because VFB = 0.6 V typ., VOUT can be calculated by using the following equation : VOUT = RFB1 + RFB2 0.6 RFB2 Connect divider resistors RFB1 and RFB2 as close to the IC as possible to minimize the effects of noise. If noise has an effect, adjust the values of RFB1 and RFB2 so that RFB1 + RFB2 < 100 k. CFB, which is connected in parallel with RFB1, is a capacitor for phase compensation. By setting the zero point (the phase feedback) by adding capacitor CFB to output voltage setting resistor RFB1 in parallel, the phase margin increases, improving the stability of the feedback loop. To effectively use the feedback portion of the phase based on the zero point, define CFB by using the following equation : CFB L COUT VOUT V 3 RFB1 DD This equation is only a guide. The following explains the optimum setting. To efficiently use the feedback portion of the phase based on the zero point, specify settings so that the phase feeds back at the zero point frequency (fzero) of RFB1 and CFB according to the phase delay at the pole frequency (fpole) of L and COUT. The zero point frequency is generally set slightly higher than the pole frequency. The following equations are used to determine the pole frequency of L and COUT and the zero point frequency set using RFB1 and CFB. 1 VDD V OUT L COUT 1 fzero 2 RFB1 CFB fpole 2 The transient response can be improved by setting the zero point frequency in a lower frequency range. If, however, the zero point frequency is set in a significantly lower range, the gain increases in the range of high frequency and the phase margin decreases. This might result in unstable operation. Determine the proper value after sufficient evaluation with actual application. The typical constants based on our evaluation are shown in Table 11.

Perform thorough evaluation using an actual application to set the constants. Precaution Mount external capacitors and inductor as close as possible to the IC. Set single point ground. Characteristics ripple voltage and spike noise occur in IC containing switching regulators. Moreover rush current flows at the time of a power supply injection. Because these largely depend on the inductor, the capacitor and impedance of power supply used, perform sufficient evaluation with actual application. The 0.1 F capacitor connected between the VOUT and VSS pins is a bypass capacitor. It stabilizes the power supply in the IC when application is used with a heavy load, and thus effectively works for stable switching regulator operation. Allocate the bypass capacitor as close to the IC as possible, prioritized over other parts. Although the IC contains a static electricity protection circuit, static electricity or voltage that exceeds the limit of the protection circuit should not be applied. The power dissipation of the IC greatly varies depending on the size and material of the board to be connected. Perform sufficient evaluation using an actual application before designing.
