SC1165 - PROGRAMMABLE SYNCHRONOUS DC/DC CONVERTER

Description

The SC1164/5 combines a synchronous voltage mode controller with two low-dropout linear regulators providing most of the circuitry necessary to implement three DC/DC converters for powering advanced ® microprocessors such as Pentium II.

Features

  • an integrated 5 bit D/A converter, pulse by pulse current limiting, integrated power good signaling, and logic compatible shutdown. The SC1164/5 switching section operates at a fixed frequency of 200kHz, providing an optimum compromise between size, efficiency and cost in the intended.
