MP2341

MP2341

24V, 2A, 1MHz, High-Efficiency, Synchronous Step-Down LED Driver in an SOT583 Package

Datasheet

Description

The MP2341 is a 24V, monolithic, synchronous, rectified, step-down switch-mode white LED (WLED) driver with built-in power MOSFETs and a synchronous rectifier switch. The MP2341 can achieve up to 2A of continuous output current (I_OUT), with excellent load and line regulation.

Peak current control mode provides fast transient response, easy loop design, and tight output regulation. Full protection features include cycle-by-cycle peak current limiting, output short-circuit protection (SCP), open LED protection, and thermal shutdown.

The MP2341 requires a minimal number of readily available, standard external components, and is available in a space-saving SOT583 package.
