Programmable Synchronous Dc/dc Converter, Dual Low Dropout Regulator Controller

The SC1164 SC1165 combines a synchronous voltage mode controller with two low-dropout linear Regulators providing most of the circuitry necessary to implement three DC/DC converters for powering advanced Microprocessors such as Pentium II. The SC1164 SC1165 switching section features an integrated 5 bit D/A Converter pulse by pulse current limiting, integrated power good signaling, and Logic compatible shutdown. The SC1164 SC1165 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 SC1164 SC1165 linear sections are low dropout regula- tors. The SC1164 supplies 1.5V for GTL bus and 2.5V for non-GTL I/O. For the SC1165 both LDOs are adjustable. By Semtech Corporation
