ZXLD1366Q AUTOMOTIVE COMPLIANT HIGH ACCURACY 1A, 60V LED DRIVER Description The ZXLD1366Q 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 1A. The ZXLD1366Q uses a high-side output current sensing circuit which uses an external resistor to set the nominal average output current. The 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 resolution can be achieved by applying a PWM signal to the ‘ADJ’ pin.
