This evaluation board user’s manual provides basic informationabout a high efficiency, low no-load power consumption referencedesign that was tailored to power All-in-One PC or similar type ofequipment that accepts 12 VDC on the input. The power supplyimplements PFC front stage to assure unity power factor and lowTHD, current mode LLC power stage to enhance transient responseand secondary side synchronous rectification to maximize efficiency.This design note focuses mainly on the NCP1399 current mode LLCcontroller description – please refer to NCP1602 and NCP4305materials to gain more information about these devices.The NCP1399 is a current mode LLC controller which means thatthe operating frequency of an LLC converter is not controlled viavoltage (or current) controlled oscillator but is directly derived fromthe resonant capacitor voltage signal and actual feedback level. Thiscontrol technique brings several benefits compare to traditionalvoltage mode controllers like improved line and load transientresponse and inherent out of zero voltage switching protection. TheLLC controller also features built-in high voltage startup and PFCoperation control pins that ease implementation of a power supplywith PFC front stage and no standby power supply on board. Theenhanced light lad operation scheme of the LLC controller allowsSMPS design to fulfill the latest no-load and light load consumptionlimits and still keep output voltage regulated with excellent transientresponse from no-load to full-load steps.
