SC1185: Programmable Synchronous DC/DC Converter, Dual LDO Controller | Semtech

The SC1185 combines a synchronous voltage mode con- troller 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, inte- grated power good signaling, and Logic compatible shut- down. The SC1185 switching section operates at a fixed frequency of 140kHz, providing an optimum compromise between size, efficiency and cost in the intended appli- cation areas. The integrated D/A Converter provides pro- grammability of output voltage from 2.0V to 3.5V in 100mV increments and 1.30V to 2.05V in 50mV incre- ments with no external components.
