Programmable Dc/dc Controller For Advanced Microprocessors - Semtech Corporation

The SC1151 voltage mode controller contains most of the circuitry necessary to implement a DC/DC con- verter for powering advanced Microprocessors such as Klamath, both in single and multiple processor con- figurations. The SC1151 features an integrated 5 bit D/A con- verter, 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, effi- ciency and cost in the intended application areas. The integrated D/A Converter provides programmabil- ity of output voltage from 2.0V to 3.5V in 100mV in- crements 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. By Semtech Corporation
