onsemi High-Voltage Switcher for Low Power Offline SMPS Switching Power Supply for NCP1060 for Power Meter SMPS

The ON Semiconductor High-Voltage Switcher for Low Power Offline SMPS NCP1060, NCP1063 products integrate a fixed frequency current mode controller with a 700V MOSFET and offers a high level of integration, including soft−start, frequency−jittering, short−circuit protection, skip−cycle, adjustable peak current set point, ramp compensation, and a Dynamic Self−Supply, it can be seamlessly used both in non−isolated and in isolated topologies, for improved standby performance, the connection of an auxiliary winding stops the DSS operation and helps to reduce input power consumption below 50 mW at high line.
