NCP1070, NCP1071, NCP1072, NCP1075, NCP1076, NCP1077 High-Voltage Switcher for Low Power Offline SMPS www.onsemi.com The NCP107x products integrate a fixed frequency current mode controller with a 700 V MOSFET. Available in a PDIP7 or SOT223 package, the NCP107x offer a high level of integration, including MARKING DIAGRAMS softstart, frequencyjittering, shortcircuit protection, skipcycle, a maximum peak current set point, ramp compensation, and a Dynamic SelfSupply (eliminating the need for an auxiliary winding). SOT223 AYW Unlike other monolithic solutions, the NCP107x is quiet by nature: ST SUFFIX z07xy during nominal load operation, the part switches at one of the available CASE 318E frequencies (65, 100 or 130 kHz). When the output power demand 1 diminishes, the IC automatically enters frequency foldback mode and provides excellent efficiency at light loads. When the power demand reduces further, it enters into a skip mode to reduce the standby PDIP7 P107xfyyy P SUFFIX consumption down to a no load condition. AWL CASE 626A YYWWG Protection features include: a timer to detect an overload or a shortcircuit event, Overvoltage Protection with autorecovery and AC input line voltage detection. Z = 1 for Std product V for Automotive For improved standby performance, the connection of an auxiliary x = Current Limit (0, 1, 2, 5, 6 or 7) winding stops the DSS operation and helps to reduce input power y = Oscillator Frequency = A (65 kHz), B (100 kHz), C (130 kHz) consumption below 50 mW at high line. yyy = 065, 100, 130 Features f = OFF phase in fault mode = P (420 ms), B (210 ms) Builtin 700 V MOSFET with R of 4.7 (NCP1076/77) / DS(on) A = Assembly Location 11 (NCP1072/75) / 22 (NCP1070/71) WL = Wafer Lot Large Creepage Distance Between Highvoltage Pins Y, YY = Year W, WW = Work Week CurrentMode Fixed Frequency Operation 65 / 100 / 130 kHz G or = PbFree Package Peak Current: NCP1070/72 with 250 mA, NCP1071 with 350 mA, NCP1075 with 450 mA, NCP1076 with 650 mA and NCP1077 with ORDERING INFORMATION 800 mA See detailed ordering and shipping information on page 28 of this data sheet.
