Description
The MP2481 is a 36V, 1.2A, white LED driver suitable for either step-down or inverting step-up/down applications. It achieves 1.2A 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, input over voltage protection, open strings protection and output short circuit protection.The MP2481 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 MP2481 requires a minimum number of readily available standard external components and is available in 8-pin MSOP8E package.
