ZXLD1362
60V 1A LED DRIVER WITH AEC-Q100
Description
Pin Assignments
The ZXLD1362 is a continuous mode inductive step-
down converter with integrated switch and high side
current sense.
VIN
LX
It operates from an input supply from 6V to 60V driving
single or multiple series connected LEDs efficiently
externally adjustable output current up to 1mA.
GND
The ZXLD1362 has been qualified to AEC-Q100 Grade 1
enabling operation in ambient temperatures from -40 to
125°C.
The output current can be adjusted by applying a DC
voltage or a PWM waveform. 100.1 adjustment of output
current is possible using PWM control.

Applying 0.2V or lower to the ADJ pin turns the output off
and switches the device into a low current standby state.
