CS5151H - CPU 4-Bit Nonsynchronous Buck Controller

Description

PIN SYMBOL VID0

FUNCTION Voltage ID DAC input pins.

These pins are internally pulled up to 5.0 V providing logic ones if left open.

The DAC range is 2.14 V to 3.54 V with 100 mV increments.

VID3 select the desired DAC o

Features

  • on board, 4.
  • bit DAC, short circuit protection, 1.0% output tolerance, VCC monitor, and programmable Soft Start capability. The CS5151H is upwards compatible with the 5.

CS5151H CPU 4−Bit Nonsynchronous Buck Controller The CS5151H is a 4−bit nonsynchronous 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 CS5151H is designed to operate over a 4.25−20 V range (VCC) using 12 V to power the IC and 5.0 V or 12 V as the main supply for conversion. The CS5151H is specifically designed to power Pentium® processors with MMX™ Technology and other high performance core logic. It includes the following features: on board, 4−bit DAC, short circuit protection, 1.0% output tolerance, VCC monitor, and programmable Soft Start capability.
