MP2341

High-Efficiency, 2A, 24V, 1MHz Synchronous, Step-Down LED Driver In SOT 583

Pre-Release

Datasheet

Description

The MP2341 is a 24V monolithic synchronous step-down white LED driver with a built-in power MOSFET and rectifier. It achieves up to 2A continue output current with excellent load and line regulation.

Peak current mode control operation provides very fast transient response and easy loop design as well as very tight output regulation.

Fault condition protection includes cycle-by-cycle 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.

Evaluation Tools

EV2341-TL-00A Evaluation Kit High-Efficiency, Synchronous Step-Down LED Driver Evaluation Board

The EV2341-TL-00A Evaluation Board is designed to demonstrate the capabilities of MP2341GTL. The MP2341 is a 24V monolithic synchronous step-down white LED driver with a built-in power MOSFET and rectifier. It achieves up to 2A continue output current with excellent load and line regulation in a tiny SOT583 package. Peak current mode operation provides fast transient response and eases loop stabilization.

The EV2341-TL-00A is typically designed for driving 2 WLEDs in series (5.9VTYP) LED load with 2A current at wide 8V to 24V input range.

The EV2341-TL-00A has high performances in efficiency, line/load regulation, deep dimming range with both analog and PWM mode. Fault condition protection includes cycle-by-cycle peak current limiting, output short circuit protection, open LED protection and thermal shutdown.
