SC1162/3 is a programmable synchronous DC/DC converter from Semtech. It integrates a low-dropout linear regulator controller and provides most of the circuitry necessary to implement two DC/DC converters for powering advanced microprocessors such as Pentium ® II.
The SC1162/3 combines a synchronous voltage mode controller with a low-dropout linear regulator to implement two DC/DC converters. The switching section features an integrated 5-bit D/A converter, pulse-by-pulse current limiting, and power good signaling, operating at a fixed frequency of 200kHz.
