AL8806Q

NOT RECOMMENDED FOR NEW DESIGN USE AL8860Q OR AL8861Q AL8806Q HIGH EFFICIENCY 30V 1.6A AUTOMOTIVE GRADE BUCK LED DRIVER Description The AL8806Q is a step-down DC/DC converter designed to drive LEDs with a constant current. The device can drive up to 8 LEDs, depending on the forward voltage of the LEDs, in series from a voltage source of 6V to 30V. The AL8806Q switches at frequencies up to 1MHz. This allows the use of small size external components, hence minimizing the PCB area needed. Maximum output current of AL8806Q is set via an external resistor connected between the VIN and SET input pins. Dimming is achieved by applying either a DC voltage or a PWM signal at the CTRL input pin. An input voltage of 0.4V or lower at CTRL switches off the output MOSFET simplifying PWM dimming. The AL8806Q has been qualified to AEC-Q100 Grade 1 and is Automotive Grade supporting PPAPs Features LED driving current up to 1.5A Better than 5% accuracy High efficiency up to 98% Optimally controlled switching speeds Operating input voltage from 6V to 30V PWM/DC input for dimming control Built-in output open-circuit protection Automotive Grade with AEC-Q100 Qualification MSOP-8EP: Available in “Green” Molding Compound (No Br, Sb)  Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)  Halogen and Antimony Free. “Green” Device (Note 3) Automotive Grade  Qualified to AEC-Q100 Standards for High Reliability  PPAP Capable (Note 4) Pin Assignments Applications Automotive...
