MP4425A - Step-Down LED Driver

General Description

The MP4425A is a high-frequency, synchronous, rectified, step-down, switch-mode white LED driver with built-in power MOSFETs.

It offers a very compact solution to achieve 1.5A of continuous output current with excellent load and line regulation over a wide input supply range.

Key Features

  • include over-current protection (OCP) and thermal shutdown (TSD). The MP4425A requires a minimal number of readily available, standard external components, and is available in a space-saving QFN-13 (2.5mmx3mm) package.

MP4425A High-Efficiency, 1.5A, 36V, 2.2MHz, Synchronous, Step-Down LED Driver DESCRIPTION The MP4425A is a high-frequency, synchronous, rectified, step-down, switch-mode white LED driver with built-in power MOSFETs. It offers a very compact solution to achieve 1.5A of continuous output current with excellent load and line regulation over a wide input supply range. The MP4425A has synchronous mode operation to get high efficiency. Current mode operation provides fast transient response and eases loop stabilization. Full protection features include over-current protection (OCP) and thermal shutdown (TSD). The MP4425A requires a minimal number of readily available, standard external components, and is available in a space-saving QFN-13 (2.5mmx3mm) package.
