Vrm9.0 Programmable, Multi-phase, High Performance Pwm Controller - Semtech Corporation

The SC1146 is the latest, high performance, multi- phase (PWM) controller designed for high power mi- croprocessors 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 channels by digitally phase shifting the PWM outputs. This ap- proach greatly reduces the stress and heat on the out- put stage components while lowering input ripple cur- rent by as much as 80%. Accurate current sharing among the four phases is achieved by precision design techniques and trimming of critical elements. The high speed transconductance error Amplifier is ex- ternally initialized using a soft-start capacitor allowing the controller to wake-up without overshoot, thus pro- tecting the low voltage Microprocessor loads. The out- put drive voltage to the Power MOSFETs is pro- grammable to minimize switching losses in the drive circuitry. By Semtech Corporation
