• Maintain stable output voltage over a range of input voltages. Useful for a wide range of applications, such as powering 5V USB devices and low voltage electronics from a 12V battery, and many other electronic projects. Constant voltage regulation, suitable for LED strips and modules, but not for raw LEDs
• Input Voltage: 4-38V DC, Output Voltage: 1.25-36V DC, Max Load: 75W/5A Peak, 50W/3.5A Sustained (whichever is lower, amps or watts)
• Conversion Efficiency: Up to 96%
• Dimensions: 66x39x18mm, XL4015 IC, 180KHz Switching Frequency
• Input must be at least 1.5V more than the output voltage. Applying reverse polarity voltage to the input or output may damage the module

This module combines the high efficiency XMLSEMI XL4015 DC-DC buck converter IC with an LED voltmeter.  The built in voltmeter makes for simple installation and adjustment and helps to monitor the supply or device power.  Voltage is adjusted using a potentiometer.  A small button switches the voltmeter between input and output.
