Internal reference voltage ( Vref ) IC internal circuitry reference voltage is provided by the temperature compensation reference voltage (5.0V). This reference voltage (Vref) provides a maximum external output current measured at the terminal of 1 mA. 2. Oscillation circuit ( OSC ) The oscillation circuit is built into the device. No external oscillation capacitor nor resistor is required. The oscillation frequency (250KHz) is set internally and has a sawtooth wave pattern. The sawtooth wave pattern cannot be outputted externally. 3. Error amplifier ( Error amp ) The error amplifier senses the DC to DC converter voltage and provides a PWM control signal output. Loop gain between the error amplifier ampOUT terminal and the negative amp terminal is determined by the connections between the feedback resistor and the capacitor. This provides stable loop compensation throughout the system. BDD200504 12-030523 4, Over-current sensor ( OCL ) The OCL is a pulse-by-pulse overcurrent sensor. The voltage drop across the external current sensing resistor is measured between the negative and positive terminals of the OCL. If the voltage drop exceeds =0.19V, the main switch (MOSFET) opens. 5. Remote ON/OFF ( R/C ) It is a remote terminal for output voltage ON/ OFF control. Output On: 0-0.5V (Ground this terminal to GND) Output Off: 2.5-5.3V (This terminal is open) 6. Soft-start (S/S ) It is a capacitor connection terminal for soft-start. The start time is delayed by connecting a capacitor which is for soft-start to this terminal. Connect a capacitor of approximately 0.1F to this terminal.

Mounting cautions Vibration and other mechanical disturbances can exert stress on the internal parts of the device. Carefully examine your equipment and place the device where vibration and other shock is minimal. 3. Soldering Conditions The infrared reflow method is recommended. If the soldering time is too long or the soldering temperature is too high, it may damage the function of this IC, so be sure to use within the specified conditions. 1) Infrared reflow method Temperature profile in the reflow method is as shown in the figure at the right. 2) Wave soldering conditions - Pre-heating conditions Center of the case temp.: 80-140C Pre-heating time: 30-60sec - Heating conditions Soldering temp.: 265+5C Heating time: 10+1sec - Heating frequency: one time - Notes Solder bridge will be effected by the land, so give consideration when designing the printed board. 3) Storage conditions After the dampproof package is opened, in an environment of temp. 30C and relative temp. 70% or below: within 168Hrs. 4) Baking conditions One time within 24Hrs. at 125C 5) Soldering Iron When using a soldering iron, execute under the following conditions. - Soldering iron tip temp.: 38010C - Heating time: 341sec - Heating frequency: one time 5 Bellnix DC-DC CONVERTERS Infrared and air reflow soidering conditions Heating sphere Within 2 cyctes Ss mee r \<= 260Cmax. = 230C Package surface temperature 4. Cleaning cautions Carefully remove all flux. Allow time for the soldered areas to completely dry before using the device. 5. Resinous Coating When remolding after mounting the device to the board, if the curing stress of the resinous is strong, it may give stress to the component. So be careful of choosing the resinous and calcify time. BDD20050412-030523Power IC BiC1422 <Usage> 1. Input protection element connection The BIC1422 device has an output current drop function. In the event of power IC device malfunction resulting in excessive input current flow, smoke and flame may be emitted from the equipment. To prevent this, install fuse or protective circuitry to the power IC device input line. Install the fuse or protective circuitry to the positive side of the input line. Be sure that the fuse or protective circuitry is not too large to effectively protect the circuitry (the input line must be capable of carrying enough current to blow the fuse). FUSE +Vi Load DC-DC Converter 2. Overvoltage protection The BIC1422 power IC device does not have an overvoltage (voltage surge) protection function. If a malfunction occurs in the device internal circuitry, there may be a voltage surge. Output will reflect this surge and damage to equipment may result. Smoke and flame may be emitted from the equipment. To prevent this, be sure to install voltage surge sensing and protection circuitry. There are a number of ways to protect against voltage surge. Figure shows a typical voltage surge protection set-up. The voltage surge sensing and protection circuit should be installed as close as possible to the load (away from the output smoothing capacitor) Reference part example Overvoltage Protection Circuit Load BDD20050412-030523 <Remote ON/OFF Control Function> The remote ON/OFF control function can be used for turning output ON and OFF without making or breaking the input. Output ON: 0-0.5V (This terminal is connected with GND) Output Off: 2.5-5.3V (This terminal is opened) - When the R/C function is not used, be sure to connect R/C terminal (Spin) and ground (4pin and 26pin). - The R/C terminal can be turned ON and Off by a switch element such as a transistor or MOSFET. However, be sure to add a condenser (1000pF-0.1 micro F) across the R/C terminal (Spin) and ground (4pin and 26pin) to prevent misoperation by noise. - Since pull-up has been carried out in the module, there is no need of impressing the voitage from the outside. 1.

But at the oblique parts it goes through D1 and the middle part goes through FET2. There are three current modes that flow into the choke. The superposed mode of direct current at rating load etc. is called C.C.M. The mode when current that flows into the choke is intermittent at light load is called D.C.M. The boundary between the C.C.M. and D.C.M. is called the critical mode. At C.C.M., the voltage applied to the choke during ton period becomes Vin-Vo, therefore the current inclination JIL will be Alt ton) = 8="2 ton When the FET1 goes off next, the current that has been flowing into the inductance will try to keep flowing into the same direction. So, it will go through D1, FET2 and start commutation. For the commutating current, the same current value of the value right before FET1 went off will flow, and the same voltage as the output voltage will be added to the both ends of L1. Therefore the current inclination AIL when off will be Vo AIL (toff) = x toff And for C.C.M. the current inclination ZIL is the same, so it will be on in = OO Vin ~ ton+toff ~ 7 To calculate the smooth choke inductance, design it so that the critical operation can be 15-20% of the rating current.
