Why Use a Buck-Boost Module?
Normal buck converters can only reduce voltage, while boost converters can only increase voltage. In many battery-powered projects, the input voltage does not stay fixed. Sometimes it is higher than the required output, and sometimes it becomes lower.
The TPS63020 solves this problem by automatically switching between buck and boost operation. This means your project can continue receiving a stable voltage even when the battery voltage changes.
Adjustable Output with Trimmer
This version includes an onboard trimmer for simple output voltage adjustment. Connect the input supply, measure the output voltage with a multimeter, and rotate the trimmer slowly until the required voltage is reached.
Always adjust and confirm the output voltage before connecting sensitive devices.
Connection Guide
- IN+ connects to positive input voltage
- IN- / GND connects to input ground
- OUT+ connects to positive output
- OUT- / GND connects to output ground
Important Notes
- Do not exceed the maximum input voltage of 5.5V.
- Always check the output voltage before connecting your load.
- Output current depends on input voltage, output voltage, cooling, and load condition.
- For high-current applications, use short and thick wires.
- Make sure the input power source can provide enough current.
- Avoid output short circuits.
