NCP1360, NCP1365 Low Power Offline Constant Current & Constant Voltage Primary Side PWM Current-Mode Controller www.onsemi.com with/without High Voltage Startup Current Source MARKING DIAGRAMS The NCP1360/65 offers a new solution targeting output power 8 levels from a few watts up to 20 W in a universalmains flyback SOIC7 XXXXX application. Thanks to a novel method this new controller saves the CASE 751U ALYWX secondary feedback circuitry (optocoupler and TL431 reference) while achieving excellent line and load regulation. 1 The NCP1360/65 operates in valleylockout quasiresonant peak current mode control mode at nominal load to provide high efficiency. TSOP6 xxxAYW When the secondaryside power starts diminishing, the switching CASE 318G frequency naturally increases until a voltagecontrolled oscillator 1 1 (VCO) takes the lead, synchronizing the MOSFET turnon in a drainsource voltage valley. The frequency is thus reduced by A = Assembly Location stepping into successive valleys until the number 4 is reached. Beyond L = Wafer Lot this point, the frequency is linearly decreased in valleyswitching Y = Year W = Work Week mode until a minimum is hit. This technique keeps the output in = PbFree Package regulation with the tiniest dummy load. Valley lockout during the first (Note: Microdot may be in either location) four drainsource valleys prevents erratic discrete jumps and provides good efficiency in lighter load situations.
