ZXLD1350Q
ZXLD1350Q is AUTOMOTIVE GRADE 350mA BUCK LED DRIVER manufactured by Diodes Incorporated.
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 350m A.
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 pliant supporting PPAPs.
