Diodes Incorporated has introduced it new LED driver, the AL9910.
With standard SO-8 and high power dissipation exposed pad SO-8 packages, the AL9910 high brightness LED driver will support universal AC input voltages from 85V to as high as 265V.
It utilizes a rugged high voltage process technology allowing it to withstand input voltage surges of up to 500V.
It delivers an output of between a few milliamps and 1A via an external MOSFET operating at a resistor programmable switching frequency up to 300kHz.
Removing the need for a start-up resistor, a built-in voltage regulator delivers a gate drive to match and protect the switching MOSFET: 7.5V for the AL9910 and 10V for the companion AL9910A.
