DESCRIPTION
The SC1162/3 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 si...
