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.
