Monolithic Power Systems NB621EV

Beschreibung

The NB621 is a high frequency synchronous rectified step-down switch mode converter with a built in internal high side power MOSFET and integrated LDO. It offers a very compact solution to achieve 8A continuous output current over a wide input, load and line range.

Current mode operation provides fast transient response and eases loop stabilization.

Full protection features include OCP and thermal shut down.

The NB621 requires a minimum number of readily available standard external components and is available in a space saving 4mm x 5mm 28-pin QFN package.
