LED Driver IC 1 Output DC DC Controller SEPIC, Step-Down (Buck), Step-Up (Boost) Analog, PWM Dimming 8-SO-EP # AL8866QSP-13 Engineering Specifications **General Description** The AL8866QSP-13 is an automotive-qualified, multi-topology DC-switching LED controller manufactured by Diodes Incorporated. It is designed to control an external power MOSFET for high-power automotive LED lighting systems. The device supports buck, boost, buck-boost and single-ended primary-inductance converter configurations. Its wide input-voltage range makes it suitable for automotive power systems and various high-voltage LED applications. The controller uses fixed-frequency peak current-mode regulation with spread-spectrum frequency modulation to reduce electromagnetic interference. It supports both analog and pulse-width-modulation dimming through the DIM input. An integrated programmable soft-start function gradually increases the inductor and switching currents during startup to reduce output-voltage and current stress. The open-drain fault output provides system-level fault reporting for abnormal operating conditions. **Engineering Specifications** **Manufacturer:** Diodes Incorporated **Manufacturer Part Number:** AL8866QSP-13 **Component Type:** Automotive LED driver controller **Converter Topologies:** Buck, boost, buck-boost and SEPIC **Control Architecture:** Fixed-frequency peak current-mode control **External Switching Device:** External power MOSFET **Minimum Input Voltage:** Four point seven volts **Maximum Input Voltage:** Eighty-five volts **Maximum Output Voltage:** Eighty-five volts **Switching Frequency:** Four hundred kilohertz **Frequency Modulation:** Spread-spectrum modulation for reduced electromagnetic interference **LED Current Control:** External current-sense resistor and external MOSFET configuration **Feedback Voltage:** Two hundred millivolts **Typical Quiescent Current:** One point eight milliamperes **Typical Efficiency:** Up to approximately ninety-three percent, depending on the application circuit and external components **Dimming Methods:** Analog dimming and pulse-width-modulation dimming **Analog Dimming Range:** One percent to one hundred percent **Analog Dimming Dynamic Range:** Greater than one hundred to one **Pulse-Width-Modulation Dimming Ratio:** One hundred to one at a two-hundred-hertz dimming frequency **Pulse-Width-Modulation Frequency Range:** Approximately one hundred hertz to one kilohertz **Full-Brightness Current Accuracy:** Approximately plus or minus three percent **Low-Level Dimming Current Accuracy:** Approximately plus or minus twelve percent at twenty-percent dimming **Soft-Start Function:** Externally programmable **Fault Output:** Active-low open-drain fault indicator **Protection Features:** Output overvoltage protection, LED open-circuit protection, output undervoltage protection, LED short-circuit protection, cycle-by-cycle overcurrent limitation, current-sense resistor short-circuit protection, inductor and diode short-circuit detection, diode open-circuit protection and thermal shutdown **Automotive Qualification:** AEC-Q100 Grade One qualified **Automotive Documentation:** PPAP capable **Manufacturing Standard:** Manufactured in IATF-certified automotive facilities **Operating Temperature Range:** Minus forty degrees Celsius to positive one hundred twenty-five degrees Celsius **Package Type:** Thermally enhanced SO-8 exposed-pad package **Pin Count:** Eight leads with exposed thermal ground pad **Mounting Style:** Surface mount **Packing Method:** Thirteen-inch tape and reel **Standard Packing Quantity:** Two thousand five hundred components per reel **Moisture Sensitivity:** Level One **Terminal Finish:** Matte-tin-plated leads **Environmental Compliance:** Lead-free, RoHS compliant, halogen-free and antimony-free **Typical Applications** Automotive high-beam and low-beam lighting Automotive daytime running lights Automotive fog lights Automotive turn-signal lights Automotive position lights Automotive brake and stop lights High-power exterior LED lighting Multi-topology automotive LED driver modules #AL8866QSP13 #AL8866Q #DiodesIncorporated #LEDDriver #AutomotiveLED #AutomotiveElectronics #BuckConverter #BoostConverter #BuckBoostConverter #SEPICConverter #PowerElectronics #LEDLighting #ElectronicComponents #EngineeringSpecifications
