60V 1A LED DRIVER WITH AEC-Q100
Description
The ZXLD1362 is a continuous mode inductive step-down converter
with integrated switch and high side current sense.
It operates from an input supply from 6V to 60V driving single or
multiple series connected LEDs efficiently externally adjustable
output current up to 1A.
The ZXLD1362 has been qualified to AEC-Q100 Grade 1 enabling
operation in ambient temperatures from -40°C 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.
