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.
