Diodes Incorporated, a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete and analog semiconductor markets, today announced that it 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 350mA, 550mA and 1A, respectively, and are designed for a broad range of automotive, architectural and industrial lighting applications.
With a typical output current accuracy better than one percent, ZXLD1356 and ZXLD1366 LED drivers provide highly accurate current matching at working voltages up to 60V. Capable of producing output powers of 30W and 48W, respectively, these TSOT23-5 and 3.0 mm x 3.0 mm DFN6 packaged LED drivers will support up to 15 LEDs in an array of applications that require minimum footprint and maximum efficiency.
Operating from a 7V to 30V supply and capable of producing an output current up to 350mA, the 2.8 mm x 2.9 mm TSOT23-5 packaged ZXLD1352 LED driver can provide up to 8W of power for driving chains up to 10 LEDs. With a large PWM dimming ratio of 1000:1, the ZXLD1352 offers highly flexible brightness control and accurate color mixing.
The ZXLD series of continuous mode inductive step-down LED drivers are characterized 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 precisely match users’ brightness requirements, and a low-level control signal turns the output off to put the LED driver into standby.
