CT1007 is a high-performance PWM controller designed for isolated flyback ACDC switching power supplies. CT1007 integrates boost power supply mode and forward power supply mode, achieving wide output voltage at low cost.

CT1020 is a high-efficiency valley switch PFC controller and configurable LLC current mode controller. PFC operation and quasi resonant (QR) valley switch mode improve work efficiency. The highly integrated CT1020 makes the LLC power supply have a very small number of components and a simple design.
