SC1151 General Description
The SC1151 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 SC1151 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 SC1151 operates at a fixed frequency of 200kHz, providing an optimum compromise between size, efficiency and cost in the intended application areas.
The integrated D/A converter provides programmability of output voltage from 2.0V to 3.5V in 100mV increments and 1.80V to 2.05V in 50mV increments with no external components.
The SC1151 provides an OVP output which can be used to trigger a crowbar circuit for true over voltage protection.
