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.
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
is qualified to AEC-Q100 Grade 1 and is
Automotive Compliant supporting PPAPs.
