CS5157 - CPU 5-Bit Synchronous Buck Controller

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.

Features

  • on board, 5-bit DAC, short circuit protection, 1.0% output tolerance, VCC monitor, and programmable soft start capability. The CS5157 is available in 16 pin surface mount. Features s Dual N-Channel Design s Excess of 1MHz Operation s 100ns Transient Response s 5-Bit DAC s Backward Compatible with Adjustable CS5120/5121 s 30ns Gate Rise/Fall Times s 1% DAC Accuracy s 5V & 12V Operation s Remote Sense s Programmable Soft Start s Lossless Short Circuit Protection.

CS5157 CS5157 CPU 5-Bit Synchronous Buck Controller 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, VCC monitor, and programmable soft start capability.
