ZXLD1350Q
AUTOMOTIVE GRADE 350mA BUCK LED DRIVER
Description
The ZXLD1350Q is a hysteretic mode inductive step-down converter
with integrated switch and high side current sense.
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.
The ZXLD1350Q has been qualified to AECQ100 grade 2 and is
Automotive Grade supporting PPAPs.

See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free,
"Green" and Lead-free.
Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl)
and <1000ppm antimony compounds.
Automotive products are AEC-Q100 qualified and are PPAP capable. Automotive, AEC-Q100 and standard products are electrically and thermally
the same, except where specified. For more information, please refer to http://www.diodes.com/quality/product_compliance_definitions/.
