NCV1072, NCV1075, NCV1076, NCV1077 Automotive High-Voltage Switcher for Low Power SMPS www.onsemi.com The NCV107x products integrate a fixed frequency current mode controller with a 670 V MOSFET. Available in a PDIP7 package, the NCV107x offer a high level of integration, including softstart, MARKING DIAGRAM frequencyjittering, shortcircuit protection, skipcycle, a maximum peak current set point, ramp compensation, and a Dynamic SelfSupply (eliminating the need for an auxiliary winding). PDIP7 V107xyyy Unlike other monolithic solutions, the NCV107x is quiet by nature: P SUFFIX AWL during nominal load operation, the part switches at one of the available CASE 626A YYWWG frequencies (65, 100 or 130 kHz). When the output power demand 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 AYW SOT223 consumption down to a no load condition. ST SUFFIX Vz7xy Protection features include: a timer to detect an overload or a CASE 318E shortcircuit event, Overvoltage Protection with autorecovery and 1 AC input line voltage detection. For improved standby performance, the connection of an auxiliary x = Current Limit (2, 5, 6 or 7) y = Oscillator Frequency winding stops the DSS operation and helps to reduce input power = A(65 kHz), B(100 kHz), 130(130 kHz) consumption below 50 mW at high line. z = 0 (with brownin), C (without brownin) yyy = 065, 100, 130 Features A = Assembly Location Builtin 670 V MOSFET with R of 4.7 (NCV1076/77) / DS(on) WL = Wafer Lot 11 (NCV1072/75) Y, YY = Year W, WW = Work Week Large Creepage Distance Between Highvoltage Pins G or = PbFree Package CurrentMode Fixed Frequency Operation 65 / 100 / 130 kHz Peak Current: NCV1072 with 250 mA, NCV1075 with 450 mA, NCV1076 with 650 mA and NCV1077 with 800 mA ORDERING INFORMATION Only limited options are released to market.
