ZXLD1362 - 6V-60V input, 1A LED driver with internal switch

Product description The ZXLD1362 is a continuous mode inductive step-down converter, designed for driving single or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage. The device operates from an input supply between 6V and 60V and provides an externally adjustable output current of up to 1A. Depending upon supply voltage and external components, this can provide up to 24 watts of output power or 16 LEDs.
