I
Description
The FA7611CP(E) is a bipolar IC containing basic circuit
necessary for PWM-type switching power supply control.
I
Features
Low-voltage operation (V
CC
= 3.6 to 22V)
Predrivers: Totem-pole output or open-collector for CH1 and
open-collector output for CH2
Latch-mode short-circuit protection function (no malfunction
due to electrical noise)
soft-start function
Undervoltage lock-out function
One capacitor shared for short circuit protection and for soft start
to minimize the number of external discrete components
I
Applications
Battery power supply for portable equipment
