Description

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 100ns response time to load transients. The CS5157H is designed to operate over a 4.25-20V range (VCC) using 12V to power the IC and 5V or 12V as the main supply for conversion.The CS5157H 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, VCCmonitor, and programmable soft start capability. The CS5157H is available in 16 pin surface mount.
