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.

IXYS Corporation has introduced an innovative inductor-less, high efficiency 1.2 A WLED driver, LDS8991, which is ideal for HB LED photoflash and torch for digital cameras, video cameras and smart phone. It can drive a HB LED at 1.2 A in FLASH mode or at 200 mA in TORCH mode, and provide full output power from a single-cell Lithium-Ion battery or supply voltage in the range from 2.7 to 5.5 V.
