CS5155

CPU 5-Bit Synchronous Buck Controller

Features

Description

The CS5155 is a 5-bit synchronous

to power Pentium^¨II processors

and other high performance core

logic. It includes the following fea-

tures: on board, 5-bit DAC, short

circuit protection, 1.0% output tol-

erance, V_CCmonitor, and pro-

grammable soft start capability. The

CS5155 is backwards compatible

with the 4 bit CS-5150, allowing the

mother board designer the capabili-

ty of using either the CS-5150 or the

CS5155 with no change in layout.

The CS5155 is available in 16 pin

surface mount and DIP packages.

■ Dual N-Channel Design

■ Excess of 1MHz Operation

■ 100ns Transient Response

■ 5-Bit DAC

dual N-Channel buck controller. It

is designed to provide unprece-

dented transient response for

todayÕs demanding high-density,

high-speed logic. The regulator

operates using a proprietary control

method, which allows a 100ns

response time to load transients.

The CS5155 is designed to operate

over a 4.25-14V range (V_CC) using

12V to power the IC and 5V as the

main supply for conversion.

■ Backward Compatible with

4 Bit CS-5150/5151 and

Adjustable CS-5120/5121

■ 30ns Gate Rise/Fall Times

■ 1% DAC Accuracy

■ 5V & 12V Operation

■ Remote Sense

The CS5155 is specifically designed

■ Programmable Soft Start

■ Lossless Short Circuit

Protection

■ V_CCMonitor
