Programmable Synchronous Dc/dc Converter With Low Dropout Regulator Controller - Semtech Corporation

The SC1162 SC1163 combines a synchronous voltage mode controller with a low-dropout linear Regulator providing most of the circuitry necessary to implement two DC/ DC converters for powering advanced Microprocessors such as Pentium II. The SC1162 3 switching section features an integrated 5 bit D/A Converter pulse by pulse current limiting, integrated power good signaling, and Logic compatible shutdown. The SC1162 3 switching section 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 con- verter provides programmability of output voltage from 2.0V to 3.5V in 100mV increments and 1.30V to 2.05V in 50mV increments with no external components. The SC1162 3 linear section is a high performance positive voltage Regulator design for either the GTL bus supply at 1.5V SC1162 or an adjustable output SC1163 . The output of the linear Regulator CAN provide up to 5A or more with the appropriate external MOSFET By Semtech Corporation
