Product Description

The MP2410A is a 24V, monolithic, synchronous, step-down, white LED driver with a built-in power MOSFET and rectifier. It achieves up to 2A of continuous output current with excellent load and line regulation. Peak current mode operation provides fast transient response and eases loop stabilization. The MP2410A incorporates both analog and PWM dimming onto a single control pin. The MP2410A implements deep analog dimming and PWM 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 MP2410A requires a minimum number of readily available, standard, external components and is available in TSOT23-6 and TSOT23-8 packages.
