SC2612 Overview

0.5 A SWITCHING CONTROLLER, 240 kHz SWITCHING FREQ-MAX, PDSO8

600kHz/200kHz
Step-Down DC/DC Converter
POWER MANAGEMENT
Description
The SC2612 is a voltage mode switcher designed for low
cost, “point of use” voltage conversion. SC2612 is avail-
able with fixed switching frequencies of 600kHz
(SC2612A) and 200kHz (SC2612C).
The SC2612 has soft start and enable functions and is
short circuit protected. The output of the switcher may
be set anywhere between 0.8V and 75% of Vin. Short
circuit protection is disabled during start-up to allow the
output capacitors time to fully charge.
