Product Description

The EV23701-QEU-00A Evaluation Board is designed to demonstrate the capabilities of MP23701. The MP23701 is a 24V monolithic synchronous step-down 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 UTQFN8(1.5mm*2.5mm) package. Peak current mode operation provides fast transient response and eases loop stabilization.

The EV23701-QEU-00A is typically designed for driving 1-2 WLEDs in series LED load with 1A LED current at wide 4.2V to 24V input range.

The EV23701-QEU-00A has high performances in efficiency, line/load regulation and deep analog dimming. Fault condition protection includes cycle-by-cycle peak current limiting, output short circuit protection, open LED protection, NTC thermal protection and thermal shutdown.

Parametrics


24V, 2A, 1.5MHz, Synchronous, Step-Down LED Driver

The MP23701 is a 24V, monolithic, synchronous, step-down, white LED driver with a built-in power MOSFET and rectifier. The MP23701 can achieve up to 2A of continuous output current with excellent load and line regulation. Peak-current mode operation provides fast transient response and easy loop stabilization.

The MP23701 implements deep analog dimming. Full protection features include cycle-by-cycle peak-current limiting, output short-circuit protection (SCP), open LED protection, NTC thermal protection, and thermal shutdown.

The MP23701 requires a minimal number of readily available, standard, external components and is available in a UTQFN-8 (1.5mmx2.5mm) package.
