8W USB DC 5V to 12V Step up Regulator Power Supply Module Step-up Converter Boost Module Electronic DIY Board

Product Parameters: Start voltage: 2V Input voltage: 2V-12V Input current: 2A Output voltage: default 12V, can be set to 9V. Other voltages can be customized. Output power: maximum 8w (input 5V case) (high easy to overheat) No-load current: less than 4mA (input 5v output 12v with LED indicator) Operating temperature: -40--80 degrees Board size: 25 * 14 * 5mm The following is a routine test data: (for reference only) Input DC2V boost to 12v output current of about 260mA Input DC3V boost to 12v output current of about 400mA or so Input DC4.2V boost to 12v output current of about 560mA Input DC5V boost to 12v output current of about 660mA Input DC8.2v boost to 12v output current of about 1100mA or so Input DC2V boost to 9v output current of about 350mA or so Input DC3V boost to 9v output current of about 530mA or so Input DC4.2V boost to 9v output current of about 740mA or so Input DC5V boost to 9v output current of about 880mA Input DC8.2v boost to 9v output current of about 1450mA Notes: 1. The module is booster board, the output voltage must be greater than the input voltage; 2. Boost efficiency at 97% -80%, the greater the output power, the lower the efficiency of 80%; 3. Pay attention to air temperature! To avoid overheating damage; 4. The output voltage is not recommended more than 6 times the input, easy to output loss of control! 5. Boost power is only less than the input power, booster plate will produce heat loss, booster board is not a generator, but the voltage conversion module. 6. For example, input 5V 2A Calculate output power: 5V * 2A * 0.8 = 8W, current: 8W / 12
