Product Summary
The SC1151CS voltage mode controller contains most of the circuitry necessary to implement a DC/DC converter for powering advanced microprocessors such as Klamath, both in single and multiple processor configurations. The SC1151CS features an integrated 5 bit D/A converter, pulse by pulse current limiting, integrated power good signaling, logic compatible shutdown and on-board over voltage protection (OVP). The SC1151CS operates at a fixed frequency of 200kHz, providing an optimum compromise between size, efficiency and cost in the intended application areas.
