ZXLD1350Q
AUTOMOTIVE COMPLIANT 350mA BUCK LED DRIVER
Description
The ZXLD1350Q is a hysteretic mode inductive step-down converter
with integrated switch and high side current sense.
Pin Assignments
(Top View)
It operates from an input supply from 7V to 30V driving single or
multiple series connected LEDs efficiently external adjustable output
current up to 350mA.
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 a voltage of 0.2V or lower to the ADJ pin turns
the output off and switches the device into a low current standby
state.
TSOT25
The ZXLD1350Q has been qualified to AEC-Q100 grade 2 and is
Automotive Compliant supporting PPAPs.
