kr A Product Line of Diodes Incorporated ZXLD1356 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.
