General Description

The AL8866Q is a Buck-Boost, Boost, Buck and SEPIC (single-ended primary-inductance converter) DC-Switching controller designed to drive an external MOSFET for high power automotive LED applications such as automotive front lighting.

The AL8866Q operates within a wide input power supply range from 4.7V to 85V.

The AL8866Q bases on a fixed-frequency, peak current-mode control architecture to incorporate spread spectrum frequency modulation technique and achieve Low EMI performance.
