30V 1A LED DRIVER with AEC-Q100

Description

The ZXLD1360 is a continuous 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 externally
adjustable output current up to 1mA.

The ZXLD1360 has been qualified to AEC-Q100 Grade 1
enabling operation in ambient temperatures from -40°C to
125°C.

The output current can be adjusted by applying a DC voltage
or a PWM waveform to the ADJ pin; 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.
