SC1144 Datasheet (Semtech Corporation) - PROGRAMMABLE/ HIGH PERFORMANCE MULTI-PHASE/ PWM CONTROLLER

SC1144, PROGRAMMABLE/ HIGH PERFORMANCE MULTI-PHASE/ PWM CONTROLLER

The SC1144 is a high performance, multi-phase (PWM) controller designed for high power microprocessors requiring ultra fast transient response, such as ® the Pentium ll and beyond.

Utilizing a novel and unique design, the controller distributes the output load across (up to) four converter channels
