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.
Soft-start can be forced using an external capacitor from the ADJ pin to ground. Applying a voltage of 0.2V or lower to the ADJ pin turns the output off and switches the device into a low current standby state.
The ZXLD1366Q has been qualified to AEC-Q100 Grade 1 and is Automotive Grade supporting PPAPs.
