MP2481

Pinout






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 MSOP8 package.
