Applications:
DIY a mobile power supply
Boost charger
Power supply for electronic equipment

Warm tips:
1. The output voltage must be higher than the input voltage.
2. The input voltage should be within 5V to 30V, other input voltage may cause damage or failure with a high probability.
3. Do not reverse the input and output interface，with no short circuit protection.
4. When working for a long time, the output current should be kept below 2.5A, and a heat sink should be used to maintain good heat dissipation.
