CS5157H

CPU 5−Bit Synchronous

Buck Controller

The CS5157H is a 5−bit synchronous dual N−Channel buck

controller. It is designed to provide unprecedented transient response

for today’s demanding high−density, high−speed logic. The regulator

operates using a proprietary control method, which allows a 100 ns

response time to load transients. The CS5157H is designed to operate

12 V as the main supply for conversion.

processors and other high performance core logic. It includes the

following features: on board, 5−bit DAC, short circuit protection,

capability. The CS5157H is available in 16 pin surface mount.
