Using dur-E-volt(TM) constant frequency peak current mode control LED driver, LED string is driven at fixed current independent of supply voltage. It operates high brightness LEDs from 8-450 Vdc sources and currents ranging from few mA to over 1 A. RoHS-compliant driver handles one to hundreds of LEDs in series or parallel combinations and exhibits 90% efficiency. LED dimming is controlled by adjusting duty cycle of PWM input pin or adjusting voltage to dimming input pin.
dur-E-volt LED Driver Provides Superior Backlighting Solutions
Chandler, AZ - Rogers Corporation, a recognized leader in manufacturing of high-performance specialty material products, introduces their new dur-E-volt(TM) 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 d ur-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.
When asked about the new dur-E-volt LED driver, Rob Kimball, general manager of Driver Electronics Solutions at Rogers, stated, "LEDs represent the lighting of the future-not only in TVs, but in general lighting. Someday soon, we'll see LEDs used to light homes, commercial and industrial buildings, as well as architectural and decorative lighting applications. With its wide input voltage range, our new LED driver meets the needs of these various market segments and applications."
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, reducing a manufacturer's Bill of Materials. It also offers the features that general lighting OEMs and LCD TV makers are looking for in an LED driver: exceptional efficiency (about 90 %,) 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.
