CS5157 General Description

The CS5157 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 100ns response time to load transients. The CS5157 is designed to operate over a 4.25-16V range (VCC) using 12V to power the IC and 5V as the main supply for conversion.

The CS5157 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, V_CC monitor, and programmable soft start capability. The CS5157 is available in 16 pin surface mount.
