LED Driver Boosts High Brightness System Performance

Oct. 21, 2010
The ZXLD1374 multi-topology LED driver promises to increase the performance of high brightness automotive, industrial, and commercial lighting systems.

The ZXLD1374 multi-topology LED driver promises to increase the performance of high brightness automotive, industrial, and commercial lighting systems. Operating in buck, boost and buck-boost modes, the driver with integrated 60V power MOSFET switch can deliver a maximum LED current of 1.5A. It features an extended input voltage range of 6V to 60V and a typical 1% output current tolerance in all topologies. Active LED thermal management is achieved via a dedicated external thermistor input and through fault diagnosis outputs reporting LED driver and load status. Additional features include dc- and PWM-dimming pins, a 1,000:1 dynamic dimming range at 500 Hz, and a 1-MHz switching frequency capability with a 100-kHz low frequency clamp. Price is $0.95 each/1,000. DIODES INC., Dallas, TX. (972) 385-2810.
