I
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.
I
Features
External synchronization input terminal
Wide supply voltage range (V
CC
=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
I
Applications
Switching power supply for general equipment
(Optimum for TV, display, and other monitor devices)
