The MP2483 is a 55V, 2.5A, white LED driver suitable for either step-down or inverting step-up/down applications. It achieves 2.5A 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, cycle-by-cycle peak current limiting, open strings protection and output short circuit protection.
