2.2 Description (continued)
穿孔塞焊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.
输出电压的控制通过一个电压模式的误差放大器和一个精确的(1%TJ= 25°C)内部电压参考值。
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, Energy Star, Energy2000, etc.).
该器件具有非常低功耗(≤70μA,前启动和<4 mA的运行),包括禁止功能适用于集成电路远程开/关,这使得它更容易符合节能规范(蓝天使,能源之星,energy2000,等等)。
An effective two-step OVP enables to safely handle over voltages either occurring at start-up or resulting from load disconnection.
The totem-pole output stage, capable of 600mA source and 800mA sink current, is suitable for big MOSFET or IGBT drive which, combined with
