Industrial Grade, 1.5A, 36V, 2.2MHz, High-Efficiency, Synchronous, Step-Down Converter



The MPQ4415M is a high-frequency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. The MPQ4415M offers a very compact solution that achieves 1.5A of continuous output current with excellent load and line regulation over a wide input supply range. The MPQ4415M uses synchronous mode operation for higher efficiency over the output current load range. Current-mode operation provides fast transient response and eases loop stabilization. Full protection features include over-current protection (OCP) and thermal shutdown. The MPQ4415M requires a minimal number of readily available, standard, external components and is available in a space-saving QFN-13 (2.5mmx3mm) package.
