ZXLD1366Q

AUTOMOTIVE COMPLIANT HIGH ACCURACY 1A, 60V LED DRIVER

Description

Pin Assignments

The ZXLD1366Q is

a continuous mode inductive step-down

(TOP VIEW)

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.

V_IN

GND

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.

I_SENSE

ADJ

(TOP VIEW)

Enhanced output current dimming resolution can be achieved by

V_IN

applying a PWM signal to the ‘ADJ’ pin.

5 GND

GND

ADJ

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.
