Produktöversikt
NCV1362AADR2G is an automotive primary side flyback controller. It is a highly integrated primary side quasi-resonant flyback controller capable of controlling rugged and high-performance off-line power supplies. Due to a Novel Method, this new controller saves secondary feedback circuitry for constant voltage and constant current regulation, achieving excellent line and load regulation without a traditional optocoupler and TL431 voltage reference. It operates in valley lockout quasi-resonant peak current mode control mode at high load to provide high efficiency. When power on secondary side starts to diminish, the controller automatically adjusts the duty cycle then at a lower load the controller enters pulse frequency modulation at a fixed peak current with a valley switching detection. This technique allows for keeping output regulation with tiny dummy load. Applications include automotive auxiliary power supplies, on-board chargers, and traction inverters auxiliary power supplies.
