The booster chip has different connections.
How to connect the booster chip depends on the specific circuit design and application scenario.
In practical use, we need to consider the power, stability and efficiency of the circuit.
There are three common booster chip connection methods: flyback boost, direct boost and current boost.
Different connection methods have different characteristics and scope of application.
For example, flyback boost is suitable for high voltage and low current scenarios, while current type boost is suitable for scenarios where a steady current needs to be provided.
Therefore, the connection of the booster chip needs to be selected according to the actual demand.
Weld the positive and negative electrodes of the original voltage according to the printed \"IN\" side. The output after voltage boost is taken as the output after voltage boost by the positive and negative wires on the \"OUT\" side.
