The MP24833 is a 55V, 3A, white LED driver suitable for step-down, inverting step up/down and step-up applications. It achieves 3A output current over a wide input supply range with excellent load and line regulation. Current mode operation provides fast transient response and eases loop stabilization. Fault condition protection includes thermal shutdown, cycle­by­cycle peak current limiting, open strings protection and output short circuit protection. The MP24833 incorporates both DC and PWM dimming onto a single control pin. The separate input reference ground pin allows for direct enable and/or dimming control for a positive to negative power conversion. The MP24833 requires a minimal number of readily-available standard external components and is available in an SOIC8E package.
