JacobsParts XL4005 5A DC Buck Step Down Voltage Converter Constant Current Adjustable Power Module (2-Pack)

Maintain stable output voltage and limit the output current over a range of input voltages. Great for general voltage conversion, battery charging, powering raw LEDs, automotive electronics, battery conversions, micro-controllers, and electronic projects.Input Voltage: 5-32V DC, Output Voltage: 0.8-30V DC, Max Load: 75W/5A Peak, 50W/3.5A Sustained (whichever is lower, amps or watts)Conversion Efficiency: Up to 95%, (our test result: 24V->12V1A: 92.7%)Input must be at least 1V more than the output voltage. Applying reverse polarity voltage to the input or output may damage the module. Dimensions: 51x26.3x14mm, XL4005 IC, 300KHz Switching Frequency
