AX9310 High Voltage LED Driver IC  GENERAL DESCRIPTION The AX9310 is an adjustable constant current driver for LED applications. A typical application for the AX9310 is to drive LED lamp with TRIAC dimmer. A special circuit is applied to produce a power factor of better than 0.9 with low input current THD. AX9310 is a controller for linear current regulator topology. Therefore, AX9310 minimizes external ponents, simplifies EMI design and lowers overall bill of materials cost. Moreover, AX9310 is manufactured by the ultra-high voltage process that can be applied to universal existing power systems. It is available in a PDIP-8L and TO252-4L package.  Features - Single Range Input Voltage (110V or 220V) - TRIAC Dimmable - High PFC Application (＞0.90 ) Constant Current LED Driver Small Size Low Cost Patent Pending Available in the 8-Pin Pb-Free PDIP and 4-Pin Pb-Free TO252 Package  BLOCK DIAGRAM Current control ISET 1/10 Axelite Confidential Materials, do not copy or distribute without written consent.
