The MPQ4425B is a high-frequency, synchronous, rectified, step-down, switch-mode white LED driver with built-in power MOSFETs. It offers a compact solution to achieve a 1.5A of continuous output current with excellent load and line regulation over a wide input supply range. Synchronous mode operation ensures high efficiency, while current mode operation provides fast transient responses and eases loop stabilization. Additional features include over-current protection (OCP) and thermal shutdown (TSD).
This device requires a minimal number of readily available, external components, and is available in space-saving QFN-13 (2.5mmx3mm) and TSOT23-8 packages.
