LED driver controller from Diodes handles more demanding lighting applications

Date Announced: 02 Feb 2012 Product newsLED Driver Controller from Diodes Handles More Demanding Lighting ApplicationsPlano, Texas – February 2nd, 2012 –-- By extending input voltage operation from 60V down to as low as 5.0V, the ZXLD1371 LED driver controller from Diodes Incorporated has been designed to handle as broad a range of applications as possible, including those subject to the greatest variance in input voltage, such as automotive lighting and 12VAC powered systems. Its ability to control an external driver FET in buck, boost and buck-boost driver topologies makes it an all-in-one solution, capable of driving as many as 20 high current LEDs in boost mode with a high level of accuracy.Employing patent pending control loops and single resistor high-side current sensing, the ZXLD1371 will deliver a typical output current tolerance of 1%, helping to produce improvements in brightness control and lamp luminance matching. The LED driver controller offers users dimming over a wide dynamic range, through separate 20:1 DC dimming and 1000:1 PWM dimming options, resulting in higher accuracy light control particularly at lower brightness levels.To further improve the reliability of LED lamp systems, the ZXLD1371 provides thermal management of LEDs via a dedicated external thermistor input, which combined with fault diagnostic outputs reporting LED load and driver status, helps to increase LED longevity. Switching at up to 1MHz, the TSSOP-16EP packaged LED driver controller will also help minimize circuit size by reducing the value of the external inductor.The ZXLD1371 LED driver controller is priced at $1.30 USD in 1k quantities.
