Product Description：
1. This product is a fixed ratio buck power converter. To ensure the normal work of the converter, the input voltage must be higher than the output voltage value of 2V or more. If there is no voltage difference of 2V, the output voltage will become lower, but the converter will not be damaged.
2. The chip works in light load mode when no load is applied, and the output voltage may vary within a certain range.
3. The output positive and negative terminals are short-circuited, and the chip starts short-circuit protection.
4. It is recommended to add a suitable fuse to the input when using.
