■ Description

The FA5301BP(N) is a bipolar IC containing basic circuits necessary for PWM-type switching power supply control. This IC switches an external transistor according to external synchronizing pulses.

■ Features

• External synchronization input terminal

• Wide supply voltage range (VCC =7 to 22V)

• Open-collector output

• Soft-start from standby mode

• Double protection of output transistor by overcurrent limiting and cutoff functions

• Output ON/OFF control function

• Not many external discrete components needed

■ Applications

• Switching power supply for general equipment(Optimum for TV, display, and other monitor devices)
