AX2006 32V,0.6A Step-down High Brightness LED Driver with 5000:1 Dimming

性能描述 GENERAL D*CRIPTION：

       The AX2006 is a continuous conduction mode inductive step-down converter, designedfor driving single or multiple series connected LED efficiently from a voltage source higherthan the total LED chain voltage. The device operates from an input supply between 8V and32V and provides an externally adjustable output current of up to 0.6A. Depending upon thesupply voltage and external components, the AX2006 can provide more than 15 watts ofoutput power. The AX2006 includes the power switch and a high-side output current sensingcircuit, which uses an external resistor to set the nominal average output current, and adedicated DIM input accepts a wide range of pulsed dimming. Applying a voltage of 0.3V orlower to the DIM pin turns the output off and switches the device into a low current standbystate.

      The AX2006 is available in SOT89-5L package.
