Programmable Synchronous Dc/dc Converter, Dual Low Dropout Regulator Controller - Semtech Corporation

The SC1182 SC1183 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 (Klamath) or Deschutes. The SC1182 SC1183 switching section features an integrat- ed 5 bit D/A Converter pulse by pulse current limiting, integrated power good signaling, and Logic compatible shutdown. The SC1182 SC1183 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 con- verter 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 compo- nents. The SC1182 SC1183 linear sections are low dropout regula- tors. The SC1182 supplies 1.5V for GTL bus and 2.5V for non-GTL I/O. By Semtech Corporation
