When using a boost power supply, please pay attention to the following points:
1. The input voltage of the power supply must be above 10V.
2. When using a switching power supply as the input power supply, connect the input power supply under no-load conditions and adjust the voltage first. Then connect the load. (Ensure that the switching power supply is always on), or adjust the voltage under no-load conditions first, then disconnect the switching power supply before connecting the load. Connect the switching power supply and the power module while the switching power supply is turned on. (Because there is a rise time when the switching power supply is turned on. When the voltage is lower than 10V, the chip is not yet working, which can easily cause the MOSFET to break down).
3. When used in constant current mode to regulate voltage, ensure that the regulated voltage must be higher than the input voltage. (For example, if the input voltage of the power supply is 12V and the no-load output voltage is 15V, do not connect a 3.2V LED light. At least connect four LEDs in series before connecting.)
