DESCRIPTION

This is a DC-DC buck-mode power module, with input voltage range 5.5~28V and fixed output voltage/current 3.3V/2.4A. 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.

Applications

Power supply for controller main-board, DIY current source, floodlight, DIY toy car, communication device, digital radio
