It may be necessary to turn the potentiometer up to 15 times before the output voltage changes This is a boost module, the output voltage must be greater than input voltage
Boost voltage to a stable regulated output. Useful for a wide range of applications, such as powering 5V USB devices from a 3.7V lithium cell, powering higher powered electronics from a 12V battery, and a wide range of automotive and electronic projects Constant voltage regulation, suitable for LED strips and modules, but not for raw LEDs
The XLSEMI XL6009 boost regulator IC has an integrated MOSFET, over-temperature protection, and over-current protection
Input: 4-32V
DC Output Voltage: 5-35V
