The AX9380, AX9370 includes a special circuit, is able to reduce AC input current distortion that allows universal operation with an extremely high PF. ideally suited for buck LED drivers.

 GENERAL DESCRIPTION
8qG嘉泰姆

The AX9380 is an average current mode control high brightness LED driver IC with
active power factor correction function.
The line and load compensations are applied in the AX9380 to improve the output
current regulation. The LED current accuracy is ±5%.
The AX9380 includes a special circuit, is able to reduce AC input current distortion that
allows universal operation with an extremely high PF. The AX9380 is ideally suited for buck
LED drivers. The IC operates in a constant off-time mode. The AX9380 also provides
system output short circuit protection.8qG嘉泰姆
