MP2341GTL-P

MP2341 is a 24V, high-efficiency 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 by cycle peak current limiting, output short circuit protection, open LED protection, overcurrent protection (OCP) and hiccup mode, overvoltage protection (OVP) with auto recovery and thermal shutdown. The MP2341 requires a minimal number of readily available, standard external components, and is available in a space-saving SOT583 package. Applications includes infrared LED drivers, general LED drivers, flashlights and handheld computer backlighting.
