Description

This reference design gives basic information about a highswitching frequency and high efficiency AC/DC power supplyreference design that provides 110 V AC (230 V AC) to 48 VDCoutput conversion. The power supply implements current modecontrol technique with enhanced load transient response. Furthermore,this design includes a fixed frequency, Continuous Conduction Mode(CCM) Power Factor Correction (PFC) control technique designed todrive the bridgeless Totem Pole PFC (TPFC) topology. The GaNswitches on the primary side enable high operating frequency whilesynchronous rectification on the secondary side maximize efficiency.This reference design provides brief information about controllers’implementation into design, their interconnections and cooperation.For more comprehensive information please refer to datasheets ofindividual parts that have been used. Please use links in literaturesection to get detail technical information about NCP1681,NCP13994, NCP4306, NCP4307, NCP1343, NCV8730, NCP718,NCP431 circuits.The NCP13994 is a high−performance current mode LLC controllerfor half bridge resonant converters. This controller implements 700 Vgate drivers, simplifying layout and reducing external componentcount. The controller is capable to drive high switching frequency andhigh−power application as well as standard low power consumerapplications. In applications where a PFC front stage is needed, theNCP13994 features an output that can be used to drive the PFCcontroller. This feature together with quiet skip mode techniquefurther improves light load efficiency of the whole application. Thecontroller provides a suite of protection features allowing safe powersupply operation in any application.
