MANCHESTER, United Kingdom - Diodes Incorporated (NASDAQ: DIOD), a leading global manufacturer and supplier of application specific standard products within the broad discrete and analog semiconductor markets, today announced that it has further extended its Zetex 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, the highly integrated ZXLD-1352, -1356 and -1366 deliver adjustable output currents of 350mA, 550mA and 1A, respectively, and suit a broad range of automotive, architectural and industrial lighting applications.

With an output current accuracy of typically better than 1%, the ZXLD1356 and ZXLD1366 provide users with highly accurate current matching at working voltages up to 60V. Capable of producing output powers of 30W and 48W respectively, these TSOT23-5 and 3mm x 3mm DFN6 packaged drivers will support up to 15 LEDs in an array of applications requiring minimum footprint and maximum efficiency.

Operating from a 7V to 30V supply and capable of producing an output current of up to 350mA, the 2.8mm x 2.9mm TSOT23-5 packaged ZXLD1352 can provide up to 8W of power for driving chains of up to 10 LEDs. With a large PWM dimming ratio of 1000:1, the driver offers highly flexible brightness control and accurate color mixing.

Continuous mode inductive step-down converters, specifically designed for driving single or multiple high brightness LEDs, the ZXLD drivers are characterized by their ease of configuration and operation. Nominal output current, set by a resistor is easily adjusted by applying a PWM or DC voltage control signal to precisely match brightness requirements; a low level control signal turns the output off and puts the driver into standby. The drivers need the support of just three discrete external components.
