CS5155H

CPU 5−Bit Synchronous

Buck Controller

The CS5155H 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 CS5155H is designed to operate

12 V as the main supply for conversion.

The CS5155H is specifically designed to power Pentium® II

processors and other high performance core logic. It includes the

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

capability. The CS5155H is backwards compatible with the 4−bit

CS5150, allowing the mother board designer the capability of using

either the CS5150 or the CS5155H with no change in layout. The

CS5155H is available in 16 pin surface mount packages.
