SC1186 - Programmable Synchronous DC/DC Converter / Dual LDO Controller

Features

  • 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.

SC1186 Programmable Synchronous DC/DC Converter, Dual LDO Controller POWER MANAGEMENT Description Features 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, 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.
