Description
SC1172 & SC1173
Programmable Synchronous DC/DC Converter with LDO Controller
Features
- The SC1172/3 combines a synchronous voltage mode controller with a low-dropout linear regulator providing most of the circuitry necessary to implement two DC/DC converters for powering advanced microprocessors such as Pentium® II . The SC1172/3 switching section features an integrated 5 bit D/A converter, pulse by pulse current limiting, integrated power good signaling, and logic compatible shutdown. The SC1172/3 switching section operates at a fixed frequency of 200kHz, providing an optimum co.
