AL8866Q Buck-Boost, Boost, Buck & SEPIC Converter

Diodes Incorporated AL8866Q Buck-Boost, Boost, Buck, and SEPIC Converter is developed to drive an external MOSFET for high-power automotive LED applications. The AL8866Q provides a 4.7V to 85V wide input power supply range. The device implements a fixed-frequency, peak current-mode control architecture to merge a spread-spectrum frequency modulation technique and reach a low EMI performance. The Buck-Boost, Boost, Buck, and SEPIC (single-ended primary-inductance converter) DC-Switching controller regulates LED current with analog or PWM dimming methods. Analog dimming response with over 100:1 Linear range is acquired by varying the voltage at the DIM pin.
