ICE3A2065ELJ数据手册集成电路（IC）的ACDC转换器离线开关规格书PDF

描述 Description

The ICE1PCS01/G is a 8-pin wide input range controller IC for active power factor correction converters. It is designed for converters in boost topology, and requires few external components.
Its power supply is recommended to be provided by an external auxiliary supply which will switch on and off the IC. The IC operates in the CCM with average current control, and in DCM only under light load condition. The switching frequency is programmable by the resistor at pin 4. Both compensations for the current and voltage loop are external to allow full user control.
There are various protection features incorporated to ensure safe system operation conditions. Examples are peak current limitation, brown-out protection and output under voltage detection. The internal reference is trimmed (5V+/-2%) to ensure precise protection and control level.
The device has an unique soft-start function which limits the start up current thus reducing the stress on the boost diode.
