ZXLD1356Q
AUTOMOTIVE GRADE 60V 550mA LED^QDRIVER
Description
The ZXLD1356Q is a continuous mode inductive step-down converter,
designed for driving single or multiple series connected LEDs efficiently
from a voltage source higher than the LED voltage. The device operates
from an input supply between 6V and 60V and provides an externally
adjustable output current of up to 550mA. Depending upon supply
voltage and external components, this can provide up to 30 watts of
output power.
Output current can be adjusted above, or below the set value, by
applying an external control signal to the ADJ pin. Enhanced output
current dimming can be achieved by applying a Pulse Width Modulated
(PWM) signal to the ADJ pin.
The ZXLD1356Q is qualified to AECQ100 Grade 1 enabling operation in
ambient temperatures from -40°C to +125°C and is Automotive
Compliant 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/.
