EVQ4425B-QB-00A

1.5A, 36V, 400kHz, High-Efficiency, Synchronous, Step-Down LED Driver Evaluation Board

Datasheet

Description

The EVQ4425B-QB-00A is an evaluation board designed to demonstrate the capabilities of the MPQ4425B, a high-efficiency, synchronous, rectified, step-down switch-mode LED driver with integrated internal high-side and low-side power MOSFETs (HS-FET and LS-FET, respectively).

The MPQ4425B offers a compact solution that can achieve up to 1.5A of continuous output current, with excellent load and line regulation across a wide input supply range. Synchronous mode offers high efficiency during all operations.

The EVQ4425B-QB-00A is a fully assembled and tested evaluation board that generates load currents up to 1.5A across a 4V to 36V input voltage (V_IN) range.
