製品説明

The MP24183 is a 55V, 1A, white LED driver suitable for either step-down or inverting step‑up/down applications. It achieves 1A peak 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, input over voltage protection, open strings protection and output short circuit protection.

The MP24183 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 MP24183 requires a minimum number of readily available standard external components and is available in 10-pin 3mm x 3mm QFN packages.
