2 Description (continued)

The highly linear multiplier includes a special circuit, able to reduce AC input current distortion, that allows

wide-range-mains operation with an extremely low THD, even over a large load range.

The output voltage is controlled by means of a voltage-mode error amplifier and a precise (1% @Tj =

25°C) internal voltage reference.

The device features extremely low consumption (

≤70 µA before start-up and <4 mA running) and includes

a disable function suitable for IC remote ON/OFF, which makes it easier to comply with energy saving

norms (Blue Angel, EnergyStar, Energy2000, etc.).

An effective two-step OVP enables to safely handle overvoltages either occurring at start-up or resulting

from load disconnection.

The totem-pole output stage, capable of 600 mA source and 800 mA sink current, is suitable for big MOS-

FET or IGBT drive which, combined with the other features, makes the device an excellent low-cost solu-

tion for EN61000-3-2 compliant SMPS's up to 300W.
