SC1150 Datasheet PDF - Semtech Corporation

DESCRIPTION
The SC1150 voltage mode controller contains most of the circuitry necessary to implement a DC/DC converter for powering the Intel Pentium® Pro microprocessor, both in single and multiple processor configurations.
The SC1150 features an integrated D/A converter, pulse by pulse current limiting, integrated power good signaling, logic compatible shutdown and on-board over voltage protection (OVP).
The SC1150 operates at a fixed frequency of 200kHz, providing an optimum compromise between size, efficiency and cost in the intended application areas.
