Bipolar IC  
For Switching Power Supply Control  
FA7622CP(E)  
Description  
Dimensions, mm  
The FA7622CP(E) is a DC-DC converter IC that can directly  
drive a power MOSFET. 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  
• Drive circuit for connecting a power MOSFET  
(Io = ±600mA)  
• Built-in voltage step-up circuit to drive a power MOSFET  
gate: A converter circuit requires only an N-channel power  
MOSFET.
