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

The input voltage must within 28V.
Load current should not be in 3A or above for a long time, otherwise it will affect the service life of the module and even burn out.
If the load current is relatively high, you should increase the minimum input voltage to ensure normal operation.
