DESCRIPTION
The SC1182/3 bines 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 (Klamath) or Deschutes. The SC1182/3 switching section Features an integrated 5 bit D/A converter, pulse by pulse current limiting, integrated power good signaling, and logic patible shutdown. The SC1182/3 switching section operates at a fixed frequency of 200kHz, providing an...
