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 provides brief information about controllers’ implementation into design, their interconnections and cooperation. Please use links in literature section to get detail technical information about NCP1618, NCP13992, NCP4306 and NCP431. The NCP1618 is an innovative multimode power factor controller. The controller automatically change operation mode depending on conditions so that the efficiency is optimized over the line and load range. In very light−load conditions, the circuit enters a soft−skip cycle mode. NCP1618 enters Continuous Conduction Mode (CCM) under Heavy−Load Conditions, while Frequency−Clamped Critical Conduction Mode (FCCrM) is used for Medium− and Light−Load Conditions. PFC−OK Output serves as Brown−Out signal for LLC controller as well as communication interface which sends NCP1618 into stand−by mode (using Soft−skip cycles).
