The SC1186 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 & III. The SC1186 switching section features an integrated 5 bit D/A converter, latched drive output for enhanced noise immunity, pulse by pulse current limiting and logic compatible shutdown. The SC1186 switching section operates at a fixed frequency of 140kHz, pro.
