Energy-efficient LED drivers
29 October 2008
Opto-Electronics
Diodes Incorporated has further expanded its Zetex ZXLD LED driver series with the introduction of three new miniature LED drivers offering improved accuracy and thermal performance. Provided in TSOT23-5 and thermally-enhanced DFN6 packages, the highly integrated ZXLD1352, ZXLD1356 and ZXLD1366 deliver adjustable output currents of 350 mA, 550 mA and 1 A respectively, and are designed for a broad range of automotive, architectural and industrial lighting applications.
With a typical output current accuracy better than 1%, the 1356 and 1366 drivers provide highly accurate current matching at working voltages up to 60 V. Capable of producing output powers of 30 W and 48 W respectively, these devices support up to 15 LEDs in an array of applications that require small footprint and high efficiency.
Operating from a 7 V to 30 V supply and capable of producing an output current up to 350 mA, the 2,8 x 2,9 mm TSOT23-5 packaged 1352 can provide up to 8 W of power for driving chains up to 10 LEDs. With a large PWM dimming ratio of 1000:1, it offers highly flexible brightness control and accurate colour mixing.
The ZXLD series of continuous-mode inductive step-down LED drivers are characterised by their simplicity of configuration and only require three simple external discrete components. Nominal output current, set by a resistor, is easily adjusted by applying a PWM or DC voltage control signal to match brightness requirements, and a low-level control signal turns the output off to put the LED driver into standby.
