NCV1077 Overview
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...
