POWER MANAGEMENT Description
The SC1185 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 SC1185 switching section features an integrated 5 bit D/A converter, pulse by pulse current limiting, integrated power good signaling, and logic compatible shutdown.
The SC1185 switching section operates at a fixed frequency of 140kHz, providing an optimum compromise between size, efficiency and cost in the intended application areas.
The integrated D/A converter provides programmability of output voltage from 2.
0V to 3.
