AL8860Q Q HIGH EFFICIENCY 40V 1.5A AUTOMOTIVE GRADE BUCK LED DRIVER 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
SET 1 8 VIN
device can operate with an input supply voltage from 4.5V to 40V and
GND 2 7 N/C
provide an externally adjustable output current up to 1.5A for MSOP-
EP T
8EP package. Depending upon supply voltage and external
GND 3 6 SW C
components, this converter can provide up to 40W output power.
U CTRL 4 5 SW D
The AL8860Q integrates the power switch and a high-side output
O
current sensing circuit, which uses an external resistor to set the
R
nominal average output current.
MSOP-8EP P
Dimming can be realized by applying an external control signal to the
Applications W
CTRL pin. The CTRL pin will accept either a DC voltage signal or a
E
PWM signal. Automotive Interior LED Lamps
N
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
Wide Input Voltage Range: 4.5V to 40V Output Current Up to 1.5A Internal 40V NDMOS Switch Typical 5% Output Current Accuracy Single Pin for On/Off and Brightness Control by DC Voltage or PWM Signal High Efficiency (>95%) LED Short-Circuit Protection Inherent LED Open-Circuit Protection Over Temperature Shutdown Up to 1MHz Switching Frequency Pb-Free MSOP-8EP Package
Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. “Green” Device (Note 3) AEC-Q100 Grade 1 Qualified (Note 4)
Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3) compliant. 2. See https://www.diodes.com/quality/lead-free/ for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free. 3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm antimony compounds. 4. Automotive products are AEC-Q100 qualified and are PPAP capable. Refer to https://www.diodes.com/quality/. AL8860Q 1 of 15 May 2019 Document number: DS41797 Rev. 2 - 2
