This evaluation board user’s manual provides basic information about a high efficiency, low no-load power consumption reference design that was tailored to power All-in-One PC or similar type of equipment that accepts 12 VDC on the input. The power supply implements PFC front stage to assure unity power factor and low THD, current mode LLC power stage to enhance transient response and secondary side synchronous rectification to maximize efficiency. This design note focuses mainly on the NCP13992 current mode LLC controller description. Please use links in literature section to get materials about NCP1616, NCP4306 and NCP431 to gain more information about these devices.The NCP13992 is a high performance current mode controller for half bridge resonant converters. This controller implements 600 V gate drivers, simplifying layout and reducing external component count. The Controller also features built-in high voltage startup. The Brown-Out input function eases implementation of the controller in all applications. In applications where a PFC front stage is needed, the NCP13992 features a dedicated output to drive the PFC controller.This feature together with quiet skip mode technique further improves light load efficiency of the whole application. The NCP13992 provides a suite of protection features allowing safe operation in any application. This includes: overload protection, over-current protection to prevent hard switching cycles, brown-out detection, open optocoupler detection, automatic dead-time adjust, over-voltage(OVP) and over-temperature (OTP) protections. The LLC current mode means that the operating frequency of an LLC converter is not controlled via voltage (or current) controlled oscillator but is directly derived from the resonant capacitor voltage signal and actual feedback level. This control technique brings several benefits compare to traditional voltage mode controllers like improved line and load transient response and inherent out of zero voltage switchingprotection.
