■ Description

The FA7615CP(E) is a bipolar IC containing basic circuit necessary for PWM-type switching power supply control. This IC can be operated by external synchronizing pulses.

■ Features

• External synchronization input terminal

• Low-voltage operation (VCC = 3.6 to 22V)

• Totem-pole predriver

• Latch-mode short-circuit protection function (no malfunction due to electrical noise)

• One capacitor shared for short-circuit protection and for soft start to minimize the number of external discrete components

■ Applications

• Battery power supply for portable equipment
