60V 550mA LED DRIVER with AEC-Q100

Description

The ZXLD1356 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.

The ZXLD1356 has been qualified to AECQ100 Grade 1

enabling operation in ambient temperatures from -40 to

125°C

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 PWM signal to the ‘ADJ’ pin.
