NCP1246 Fixed Frequency Current Mode Controller for Flyback Converters The NCP1246 is a new fixedfrequency currentmode controller featuring the Dynamic SelfSupply. This function greatly simplifies www.onsemi.com the design of the auxiliary supply and the V capacitor by activating CC the internal startup current source to supply the controller during MARKING startup, transients, latch, standby etc. This device contains a special DIAGRAM HV detector which detect the application unplug from the AC input 8 line and triggers the X2 discharge current. This HV structure allows 46XXfff the brownout detection as well. ALYWX SOIC7 It features a timerbased fault detection that ensures the detection of CASE 751U 1 overload and an adjustable compensation to help keep the maximum power independent of the input voltage. 46XXfff= Specific Device Code Due to frequency foldback, the controller exhibits excellent XX = A, B or AL fff = 065 or 100 efficiency in light load condition while still achieving very low A = Assembly Location standby power consumption. Internal frequency jittering, ramp L = Wafer Lot compensation, and a versatile latch input make this controller an Y = Year excellent candidate for the robust power supply designs. W = Work Week A dedicated Off mode allows to reach the extremely low no load = PbFree Package input power consumption via sleeping whole device and thus minimize the power consumption of the control circuitry.

Flyback Converter Application Using the NCP1246 PIN FUNCTION DESCRIPTION Pin No Pin Name Function Pin Description 1 LATCH LatchOff Input Pull the pin up or down to latchoff the controller. An internal current source allows the direct connection of an NTC for over temperature detection. 2 FB Feedback + Shutdown pin An optocoupler collector to ground controls the output regulation. The part goes to the low consumption Off mode if the FB input pin is pulled to GND. 3 CS Current Sense This Input senses the Primary Current for currentmode operation, and offers an overpower compensation adjustment. 4 GND The controller ground 5 DRV Drive output Drives external MOSFET 6 VCC VCC input This supply pin accepts up to 28 Vdc, with overvoltage detection. The pin is connected to an external auxiliary voltage. It is not allowed to connect another circuit to this pin to keep low input power consumption. 8 HV Highvoltage pin Connects to the rectified AC line to perform the functions of Startup Current Source, SelfSupply, brownout detection and X2 capacitor discharge function and the HV sensing for the overpower protection purposes. It is not allowed to connect this pin to DC voltage. www.onsemi.com 2
