DESCRIPTION
The SC1164/5 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 SC1164/5 switching section features an integrated 5 bit D/A converter, pulse by pulse current limiting, integrated power good signaling, and logic compatible shutdown. The SC1164/5 switching section operates at a fixed frequency of 200kHz, 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 3.5V in 100mV increments and 1.30V to 2.05V in 50mV increments with no external components. The SC1164/5 linear sections are low dropout regulators. The SC1164 supplies 1.5V for GTL bus and 2.5V for non-GTL I/O. For the SC1165 both LDO’s are adjustable.FEATURES
