DATA SHEET www.onsemi.com 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 compensation, and a Dynamic Self Supply (elimi.

NCV1077 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
