SC1189 Datasheet | SEMTECH

Programmable Synchronous DC/DC Converter, Dual LDO Controller POWER MANAGEMENT Description Features The SC1189 bines 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®III. The SC1189 switching section Features an integrated 5 bit D/A converter, latched drive output for enhanced noise immunity, pulse by pulse current limiting and logic patible shutdown. The SC1189 switching section operates at a fixed frequency of 200kHz, providing an optimum promise between size, efficiency and cost in the intended application...
