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
