描述 Description

Enhanced Off-line SMPS Controller With Hiccup and Cycle-SkippingThe IN-PLUG IPS18 is an enhanced off-line switcher version of the IPS10. It includes additional features such as soft start and over-voltage limiting. Like the IPS10, the IPS18 was designed for low-cost, high-efficiency, low-power flyback off-line switching power supplies. It contains a shunt-regulator, a precision oscillator, a PWM with its associated comparator and loop compensation components as well as all the necessary biasing and protection circuitry (thermal shutdown, under-voltage, over-voltage and over-current).
