Product Description

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 (VCC) 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, 1.0% output tolerance, VCC monitor, and programmable Soft Start 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.
