DESCRIPTION The MP2341 is a 24V, monolithic, synchronous, rectified, step-down, switch-mode white LED driver with built-in internal power MOSFETs and a synchronous rectifier switch. The MP2341 achieves up to 2A of continuous output current with excellent load and line regulation. Peak current mode control operation provides fast transient response, easy loop design, and tight output regulation. Fault condition protection includes cycle-bycycle peak current limiting, output short circuit protection, 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. MP2341 High-Efficiency, 2A, 24V, 1MHz, Synchronous, Step-Down LED Driver in SOT583 Package FEATURES  Wide 4.
