NB650 - MPS

NB650 Synchronous Step-Down Converter

The NB650/NB650H is fully-integrated, highfrequency, synchronous, rectified, step-down, switch-mode converters with dynamic-output– voltage control. It offers a very compact solution to achieve 6A of continuous output current over a wide input supply range, and has excellent load and line regulation. The NB650/NB650H operates at high efficiency over a wide o.

Features

include short-circuit protection, over-current protection, over-voltage protection, under-voltage protection, and thermal shut down. The NB650/NB650H requires a minimal number of readily-available standard external components, and is available in a space-saving 3mm×4mm QFN17 package. FEATURES
