It fulfills the requirements of minimum external control circuitry for a flyback application. Current mode control means that the current through the MOS transistor is compared with a reference signal derived from the output voltage of the flyback application. The result of that comparison determines the on time of the MOS transistor. To minimize external circuitry the sense resistor which gives information about MOS current is integrated. The oscillator resistor and capacitor which determine the switching frequency are integrated, too. Special efforts have been made to compensate temperature dependency and to minimize tolerances of this resistor. The circuit in detail: (see Figure 3) Start Up Circuit (uvlo) Uvlo is monitoring the external supply voltage VCC. When VCC is exceeding the on threshold VCCH = 12 V, the bandgap, the bias circuit and the soft start circuit are switched on. When VCC is falling below the off-threshold VCCL = 9 V the circuit is switched off. During start up the current consumption is about 30 A. Bandgap (bg) The bandgap generates an internal very accurate reference voltage of 5.5 V to supply the internal circuits. Current Source (bias) The bias circuit provides the internal circuits with constant current. Oscillator (osc) The oscillator is generating a frequency twice the switching frequency fswitch = 100 kHz. Resistor, capacitor and current source which determine the frequency are integrated. The charging and discharging current of the implemented oscillator capacitor is internally trimmed, in order to achieve a very accurate switching frequency. Temperature coefficient of switching frequency is very low (see Page 18). Divider Flip Flop (tff) Tff is a flip flop which divides the oscillator frequency by one half to create the switching frequency. The maximum duty cycle is set to Dmax = 0.5. Data Sheet 9 2002-08-08 TDA 16831-4 Circuit Description Current Sense Amplifier (pwmop) The positive input of the pwmop is applied to the internal sense resistor. With the internal sense resistor (Rsense) the sensed current coming from the CoolMOS is converted into a sense voltage. The sense voltage is amplified with a gain of 32 dB. The amplified sense voltage is connected to the negative input of the pwm comparator. Each time when the CoolMOS transistor is switched on, a current spike is superposed to the true current information. To eliminate this current spike the sense voltage is smoothed via an internal resistor capacitor network with a time constant of Td1 = 100 ns. This is the first leading edge blanking and only a small spike is left. To reduce this small spike the current sense amplifier is creating a virtual ramp at the output. This is done by a second resistor capacitor network with Td2 = 100 ns and an op-offset of 0.8 V which is seen at the output of the amplifier. When gate drive is switched off the output capacitor is discharged via pulse signal pwmpls. The oscillator signal slogpwm sets the RS-flip-flop. The gate drive circuit is switched on, when capacitor voltage exceeds the internal threshold of 0.4 V. This leads to a linear ramp, which is created by the output of the amplifier. Therefore duty cycle of 0% is possible. The amplifier is compensated through an internal compensation network. The transfer function of the amplifier can be described as Ki Vo - ; p = j ------ = ----------------------------------p x (1 + T x p) Vi the step response is described with -t on -------- T V o = V i x K i x t on - T + T x e 40K i = ----t on T = 850 ns Comparator (pwmcomp) The comparator pwmcomp compares the amplified current signal pwmrmp of the CoolMOS with the reference signal pwmin. Pwmin is created by an external optocoupler or external transistor and gives the information of the feedback circuitry. When the pwmrmp exceeds the reference signal pwmin the comparator switches the CoolMOS off. Data Sheet 10 2002-08-08 TDA 16831-4 Circuit Description Logic (logpwm) The logic logpwm comprises a RS-flip-flop and a NAND-gate. The NAND-gate insures that CoolMOS transistor is only switched on when sosta is on and pwmin has exceeded minimum threshold and pwmin is below pwmrmp and currentshutdown is off and tempshutdown is off and tff sets the starting impulse. CoolMOS transistor is switched off when pwmrmp exceeds pwmin or duty cycle exceeds 0.5 or pwmcs exceeds Imax or silicon temperature exceeds Tmax or uvlo is going below threshold. The RS-flip-flop ensures that with every frequency period only one switch on can occur (double pulse suppression). Gate Drive (gtdrv) Gtdrv is the driver circuit for the CoolMOS and is optimized to minimize EMI influences and to provide high circuit efficiency. This is done by smoothing the switch on slope when reaching the CoolMOS threshold. Leading switch on spike is minimized then. When CoolMOS is witched off, the falling slope of the gate driver is slowed down when reaching 2 V. So an overshoot below ground can't occur. Also gate drive circuit is designed to eliminate cross conduction of the output stage. Current Shut Down (cssd) Current shut down circuit switches the CoolMOS immediately off when the sense current is exceeding an internal threshold of 100 mV at Rsense. Tempshutdown (tsd) Tempshutdown switches the CoolMOS off when junction temperature of the PWM controller is exceeding an internal threshold.
