ZXLD1356 60V 550mA LED DRIVER and AUTOMOTIVE GRADE

The ZXLD1356 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 curre.

ZXLD1356 Features

* Typically better than 0.8% output current accuracy

* Simple and with low part count

* Single pin on/off and brightness control using DC voltage or PWM

* PWM resolution up to 1000:1

* High efficiency (up to 97%)

* Wide input voltage range: 6V to 60V
