MP24833-A

The Future of Analog IC Technology DESCRIPTION The MP24833-A is a 55V, 3A, white LED driver suitable for step-down, inverting step-up/stepdown, and step-up applications. The MP24833A achieves 3A of output current with excellent load and line regulation over a wide input supply range. Current mode operation provides a fast transient response and eases loop stabilization. Full protection features include thermal shutdown, cycle-by-cycle peak current limiting, open-string protection, and output short-circuit protection (SCP). The MP24833-A incorporates both DC and PWM dimming into 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-A requires a minimal number of readily available, standard, external components and is available in a SOIC-8 EP package.
