Programmable, High Performance Multi-phase, Pwm Controller

The SC1144 is a high performance, multi-phase (PWM) controller designed for high power micropro- cessors 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 by digitally phase shifting the PWM outputs. This approach greatly reduces the stress and heat on the output stage components while lowering input ripple current by as much as 80%. Accurate current sharing among the four phases is achieved by precision design tech- niques and trimming of critical elements. The high speed transconductance error Amplifier is externally initialized using a soft-start capacitor allow- ing the controller to wake-up without overshoot, thus protecting the low voltage Microprocessor loads. The output drive voltage to the Power MOSFETs is pro- grammable to minimize switching losses in the drive circuitry. By Semtech Corporation
