Features
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 1mA.
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.
