dur-E-volt LED Driver Propels the Light

Written by Margo Lakin
Wednesday, 01 October 2008
Rogers Corporation introduces dur-E-volt LED driver, a constant-frequency, peak current mode control LED driver. The product allows an LED string to be driven at a fixed current, separate from the supply voltage. This provides improved reliability and constant light output. The dur-E-volt LED driver is able to support anywhere from one to hundreds of LEDs in series or parallel combinations, using fewer components. It is compact in size and is reported to be 90% efficient and to have excellent heat dissipation. High brightness LEDs (HBLEDs) from 8 VDC to 450 VDC can be supported efficiently. LED dimming can be controlled by two methods: by the PWM input pin or by adjusting the voltage to the LD/Linear Dimming pin. The driver is RoHS and WEEE complaint. www.rogerscorp.com/durel
