ME8401 优势与功能:推MOS管,BOOST模式,PFM控制模式,外加PWM驱动可做300W以下开关电源,90W以下单级PFC LED驱动.

 

MD8401 可替代L6562,L6561,FAN6961

 

ME8401是一款专门针对功率因数校正而设计的控制芯片。主要针对300W以内开关电源、适配器、充电器而设计。全电压范围内可以轻松做到非常高PF值、很小的总谐波失真电流(THD)。内部的乘法器带有最优化的THD专门电路,能有效地控制AC输入电流的交越失真和误差放大器输出纹波失真,从而提高功率因数和降低(THD)。

 

主要特点

宽电源电压范围(10.5-21V)、内部THD优化电路

极低的启动电流(110uA)和工作电流(1.8mA)

峰值电流控制模式(工作在临界TM状态)

推挽式驱动输出,高达+800mA/-600mA的驱动电流

内部参考电压精度为1%以内

可调的外部过电压保护,能有效的处理开机和负载变化时产生的过电压

内置电流检测低通滤波器

封装形式:SOP-8、DIP-8

 

General Description

The ME8401 is a current-mode PFC controller operating in Transition Mode (TM). Pin-to-pin compatible with the predecessor ME8401, it offers improved performance. 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 (≤120 uA before start-up and <2mA 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 overvoltage 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 MOS-FET or IGBT drive which, combined with the other features, makes the device an excellent low-cost solution for EN61000-3-2 compliant SMPS's up to 300W.
