FA7613CP Datasheet, PDF (1/5 Pages) Fuji Electric – Bipolar IC For Switching Power Supply Control

FFAA76173C6P(1E) 3CP(E)
s Description
The FA7613CP(E) is a bipolar IC containing basic circuit
necessary for PWM-type switching power supply control. The
supply voltage range is from 2.5V.
s Features
• Low-voltage operation (VCC = 2.5 to 22V)
• Open collector output
• Latch-mode short-circuit protection function (no malfunction
due to electrical noise)
• Soft-strat function
• Output ON/OFF control function
• Low standby current (Max. 10µA)
• Not many external discrete components needed
s Applications
• Battery power supply for portable equipment
