High Efficiency DC:DC Converter Has Dual Digital Control for LED Lighting
May 2008 - Powerstax plc, market leading providers of high efficiency application rich power solutions, announce the availability of a new DC:DC converter for the rapidly growing LED lighting market. This compact high efficiency DC:DC converter has a wide input range, from 11 to 36VDC, and provides a constant current single output, variable from 100mA to 2A, to provide power for a single LED through to an array of up to 9.
Two digital control functions are provided to enable lighting designers' maximum flexibility. An I²C bus allows the output current to be set to ensure correct power is provided to the LED lamp or array in use. The second control input is for a PWM signal to allow the LED light output to be varied. To ensure smooth lamp dimming across a wide intensity range while maintaining the correct LED light colour the PWM controller has a 12 bit resolution.
Tim Worley, CEO of Powerstax plc, comments, "We now have considerable experience in providing high efficiency power solutions to the LED lighting market. Our core competence of providing flexible, very high efficiency power solutions makes us ideal partners for LED lamp manufacturers. Our new DC:DC converter offers up to 90% efficiency in a very compact package while providing sophisticated digital control functions."
The new Powerstax DC:DC converter measures just 61 x 61 x 20mm, and has an operating temperature range of typically -55 to 105ºC without derating.
Typical applications include architectural lighting solutions for public buildings, museums, shopping malls, hospitals and schools. For more information visit www.powerstaxplc.com, email sales@powerstaxplc.com or call +44 (0)1252 407800
