IXYS Corporation has released an innovative inductor-based 6-channel White LED driver LDS8763, which can drive up to 72 WLEDs in six strings with up to 12 LEDs per string.

The LDS8763 is delivered with factory programmed LED current at 20, 25, or 30 mA per string and 1.5% channel-to-channel current matching.

Internal PWM pulse generator with duty cycle regulated by external DC voltage applied to the PWM pin adjusts its LED brightness.

Duty cycle changes linearly from 1% at 0.25 V to 100% at 1.135 V and remains at 100% at higher voltages.

With an internal MOSFET switch as a synchronous rectifier, the LDS8763 operates at 0.7 MHz switching frequency and wide input voltage range of 4.5 to 28 V for power conversion circuitry.

It is available in backlight LED lighting of medium size LCD displays like notebooks, netbooks, E-books, tablet computers, navigation displays, small LCD TVs and displays as well as large area LED lighting panels for indoors and outdoors LED lighting fixtures.
