DATA SHEET .onsemi. Automotive High-Voltage Switcher for Low Power SMPS NCV1072, NCV1075, NCV1076, NCV1077 The NCV107x products integrate a fixed frequency current mode controller with a 670 V MOSFET. Available in a PDIP- 7 package, the NCV107x offer a high level of integration, including soft- start, frequency- jittering, short- circuit protection, skip- cycle, a maximum peak current set point, ramp pensation, and a Dynamic Self- Supply (eliminating the need for an auxiliary winding). Unlike other monolithic solutions, the NCV107x is quiet by nature: during nominal load operation, the part switches at one of the available frequencies (65, 100 or 130 k Hz). 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 consumption down to a no load condition. Protection Features include: a timer to detect an overload or a short- circuit event, Overvoltage Protection with auto- recovery and AC input line voltage detection. For improved standby performance, the connection of an auxiliary winding stops the DSS operation and helps to reduce input power consumption below 50 m W at high line.
