Monolithic Power Systems NB621
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. 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.DESCRIPTION
Current mode operation provides fast transient response and eases loop stabilization. Full protection features include OCP and thermal shut down. END OF LIFE, REFER TO NB700 OR NB693AFEATURES
