VRM9.0 PROGRAMMABLE, MULTI-PHASE, HIGH PERFORMANCE PWM CONTROLLER July 25, 2000 SC1146 TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.com DESCRIPTION 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 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%.
