Module Properties: non-isolated step-up / step-down module; Input Voltage: 5~32V; Input Current: 8A (max.) Peak 10A (within 6A in long time natural radiating heat operating); Quiescent Current: 4mA (there will be errors when the operating voltage is not the same); Output voltage: 1.25~20V (adjustable default output 12V); Output Current: 5A Max. (within 3A in long time natural radiating heat); Output current range: 0.2~5A; Operating temperature: -40 to +85 degrees; Operating Frequency: 150KHz; Conversion efficiency: Up to 96%; Current protection: Yes; Short circuit protection: Yes (input 10A fuse); Over-temperature protection: Yes (automatically reduce the output voltage when -over-temperature); Input Reverse Polarity Protection: None; Installation: Four 3mm screws; Wiring: Solder terminal ("V-IN" is the input "V-OUT" is the output); Applications: 1. DIY a stabilized power supply input 12V output 1.2~20V (adjustable); 2. It can provide power for electronic devices according to system set output voltage value; 3. It can be used as a car power which supplies power for laptop PDA or a variety of digital products; 4. DIY a mobile power laptop power with 12V large-capacity lithium battery pack; 5. Solar panel regulator; 6. Supply power for the battery lithium battery. 7. Driving high-power LED lights.
