Beschreibung
This evaluation board user’s manual provides elementaryinformation about a high efficiency, low no-load power consumptionreference design that is targeting power laptop adapter or similar typeof equipment that accepts 19.5 VDC on the input.The power supply implements PFC front stage to assure unity powerfactor and low THD, current mode LLC power stage to enhancetransient response and secondary side synchronous rectification tomaximize efficiency. This design focuses mainly on the NCP1399current mode LLC controller description – please refer to NCP1602and NCP4305 material 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.The enhanced light lad operation of the LLC controller allowsSMPS design to pass the latest no-load and light load consumptionlimits and still keeping output regulated with excellent transientresponse from no-load to full-load steps.
