NB633EL - Synchronous Step-down Converter

Download the NB633EL datasheet PDF. This datasheet also covers the NB633 variant, as both devices belong to the same synchronous step-down converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The NB633 is a high frequency synchronous rectified step-down switch mode converter with built in internal power MOSFETs.

It offers a very compact solution to achieve 3A continuous output current over a wide input supply range with excellent load and line regulation.

Key Features

  • include OCP and thermal shut down. The NB633 requires a minimum number of readily available standard external components and is available in a space saving 3mm x 4mm 14-pin QFN package. END OF LIFE, REFER TO NB691A OR NB692.
