Rogers introduces LED driver

A Rogers Corp product story

Edited by the Electronicstalk editorial team Oct 3, 2008

Rogers Corporation has introduced its dur-E-volt high-voltage, constant frequency peak current mode control LED driver.

Using the dur-E-volt LED driver, an LED string is driven at a fixed current that is independent of the supply voltage.

This enables constant light output and enhanced device reliability.

The dur-E-volt LED driver provides efficient operation of high brightness LEDs (HBLEDs) from voltage sources ranging from 8VDC to 450VDC and currents ranging from a few mA up to over 1A.

LED dimming is controlled by adjusting the duty cycle of the PWM input pin or adjusting the voltage to the dimming input (LD/Linear Dimming) pin.

The dur-E-volt LED driver can handle from one to hundreds of LEDs in series or parallel combinations, which means it uses fewer components.

It also offers the features that general lighting OEMs and LCD TV makers are looking for in an LED driver: exceptional efficiency (about 90 per cent,) small size and superior heat dissipation.

All of Rogers' IC drivers, including the new dur-E-volt LED driver, are RoHS (Restriction of Hazardous Substances) and WEEE (Waste of Electric and Electronic Equipment) compliant.
