Bipolar IC  
For Switching Power Supply Control  
FA7630CP(E)  
Description  
Dimensions, mm  
The FA7630CP(E) is dual channel PWM-type switching power  
supply control IC.  
This IC can drive Pch-MOSFET directly and is optimum for  
large power DC-DC converter.

This IC has all the necessary protection functions for a power  
MOSFET. It is optimum for a portable equipment power  
supply which uses low-voltage input to output comparably  
large power.  
Features  
• Dual channel PWM-type switching power supply control  
±2.6% (VREF) and ±3% (VB) reference voltage  
• Low voltage operation (Vcc: 5 to 20V)  
• Drive circuit for connecting a Pch-MOSFET  
• Overload cutoff circuit with timer latch circuit  
• Soft start circuit

• Undervoltage lockout function (UVLO)  
• Pulse-by-pulse overcurrent limiting function  
• Output ON/OFF control function for each channel  
• Master-slave synchronized operation without external  
components
