SC1146 - Semtech Corporation

SC1146 VRM9.0 PROGRAMMABLE/ MULTI-PHASE/ HIGH PERFORMANCE PWM CONTROLLER

The SC1146 is the latest, high performance, multiphase (PWM) controller designed for high power microprocessors requiring ultra fast transient response. The SC1146 is programmable for the voltage range required by the latest Microprocessors . Utilizing a novel and unique design, the controller distributes the output load across (up to) four converter channel.
