MPS MP2481DH-LF

Регулятор постоянного тока DC4.5V36V1.2A

Overview

The MP2481DH-LF 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, cycle­by­cycle peak current limiting, input over voltage protection, open strings protection and output short circuit protection. The MP2481DH-LF 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 MP2481DH-LF requires a minimum number of readily available standard external components and is available in 8-pin MSOP8 package.
