AUTOMOTIVE GRADE BUCK LED DRIVER NEW PRODUCT Description Pin Assignments
(Top View) The AL8860Q is a hysteresis mode DC/DC step-down LED driver,
designed for driving single or multiple series of the connected LEDs
efficiently from a voltage source higher than the LED voltage. The
device can operate with an input supply voltage from 4.5V to 40V and
provide an externally adjustable output current up to 1.5A for MSOP8EP package. Depending upon supply voltage and external
components, this converter can provide up to 40W output power. 1 GND 2 8 VIN 7 N/C EP The AL8860Q integrates the power switch and a high-side output
current sensing circuit, which uses an external resistor to set the
nominal average output current.
Dimming can be realized by applying an external control signal to the
CTRL pin. The CTRL pin will accept either a DC voltage signal or a
PWM signal. SET GND 3 6 SW CTRL 4 5 SW MSOP-8EP Applications

 Automotive Interior LED Lamps
Automotive Exterior LED Lamps The soft-start time can be adjusted by connecting an external
capacitor from the CTRL pin to the ground. Applying a voltage of 0.2V
or lower to the CTRL pin can turn off the switch and make the device
enter into the standby mode with low power consumption.
The AL8860Q is qualified to AEC-Q100 Grade 1 and is automotive
grade to support PPAPs. Features …
