AL8866 BUCK AND SEPIC LED CONTROLLER

The AL8866 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 LED applications. The AL8866 operates within a wide input power supply range from 4.7V to 85V. Based on a fixed-frequency, peak c.
