LED Drivers Offer Multiple Dimming Options

The LDU series 300 mA to 1A PCB-mount LED drivers have a typical efficiency of 95% and offer constant current outputs of 300, 350, 500, 600, 700, or 1,000 mA. Supporting input voltages from 7 to 30 Vdc, dimming options include analog methods of voltage or resistance or a PWM input signal. The PWM approach has a maximum operating frequency of 1 kHz with a minimum 200-ns on/off time. When using an analog dimming method, the output current range is adjustable from 25% to 100% of nominal current. Prices start from $7.80 for the LDU08 300-mA unit to $13.26 for LDU24 1,000-mA unit in medium quantities. For further information, contact Duane Darrow at XP POWER, Sunnyvale, CA. (408)732-7777.
