DC-DC Buck-Mode Power Module (5.5~28V to 3.3V

3A)

SKU:DFR0570



INTRODUCTION

This is a DC-DC buck-mode power module, with input voltage range 5.5~28V and fixed output

voltage/current 3.3V/3A. Its work frequency can reach to 0.5MHz. The module has high

conversion and tiny body, convenient to embed.

Besides, it has steady output voltage, which can work long time without voltage shift and is

suitable for the occasion with high requirements. The product can work with high-capacity and

high-voltage batteries to DIY mobile powers. It can also be embedded into projects to provide

multiple power options.
