AX9380 (Preliminary) Universal High Brightness Led Driver  GENERAL DESCRIPTION The AX9380 is an average current mode control high brightness LED driver IC with active power factor correction function. The line and load pensations 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.  Features Universal Rectified 90VAC to 264VAC Input Voltage Range Built-in Active Power Factor Correction Technique Constant Current Control LED Driver High Efficiency Application Built-in Output Short Circuit Protection Constant Off-Time No External Loop pensation ponents Required Very Tight Line and Load Regulation Available in the 8-Pin Pb-Free SOP Package  BLOCK DIAGRAM 1/10 Axelite Confidential Materials, do not copy or distribute without written consent.
