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

Buck-Boost Switching Regulator IC Positive Adjustable (Fixed) 6.5V (11.5V) 1 Output 6A 22-PowerWFQFN The MAX25239/MAX25240 are small, synchronous, buck-boost converters with integrated H-bridge switches. These ICs provide a fixed-output regulation voltage and an externally adjustable output voltage in the 3V to 20V range with an input voltage above, below, or equal to the output regulation voltage. The ICs have typical 8.2A and 10A input current limit options and can support continuous load currents up to 6A depending on the input-to-output voltage ratio and operating frequency. It also has a wide input voltage range of 2V to 36V. The MAX25239/MAX25240 have three switching frequency options: 2.1MHz, 400kHz, and 200kHz. The 2.1MHz high switching frequency allows small external components and reduced output ripple, and guarantees no AM band interference, while the 400kHz or 200kHz switching frequency offers better efficiency and relieves the power consumption concern. The SYNC input allows three operation modes: skip mode with ultra-low quiescent current, forced fixed-frequency PWM operation, and synchronization to an external clock. The IC also includes spread-spectrum frequency modulation to minimize EMI interference. The MAX25239/MAX25240 feature a power-OK (POK) indicator, undervoltage lockout, overvoltage protection, cycle-by-cycle current limit, and thermal shutdown. The ICs are available in small, 4.25mm x 4.25mm x 0.75mm, 22-pin FC2QFN and 5.00mm x 5.00mm x 0.75mm, 18- pin FCQFN packages.
