SC4812: Primary Side PoE PWM Controller | Semtech

The SC4812 is a highly integrated current mode PWM controller designed for isolated or non-isolated DC-DC con- verters in telecommunication and data Communication applications. It minimizes the amount of external Discrete components needed and leads to substantial cost and space saving converter designs. The circuitry of the SC4812 includes an integrated high voltage start-up circuit suitable for telecom/industrial voltage applications. It is disabled during regular opera- tion and improves efficiency. Current mode control with leading-edge blanking simplifies control loop design and internal ramp compensation circuit stabilizes the current loop when operating above 50% duty cycle. Internal er- ror Amplifier could be used for non-isolated applications. By Semtech Corporation
