CS5155

CPU 5−Bit Synchronous

Buck Controller

The CS5155 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 CS5155 is designed to operate

over a 4.25−14 V range (V ) using 12 V to power the IC and 5.0 V as

the main supply for conversion.

The CS5155 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 CS5155 is backwards compatible with the 4−bit

CS5150, allowing the mother board designer the capability of using

either the CS5150 or the CS5155 with no change in layout. The

CS5155 is available in 16 pin surface mount and DIP packages.
