DC-DC 3V-25V To 5-25V 3A Adjustable Non Isolated High Efficiency Boost Power Module Lithium Battery Solar Step Up Board

Description:The input is 3-25v to 5v-25v to adjust the output arbitrarily, the input current up to 3A, can be used for various occasions to boost electronic products, boost ratio as high as 4 or more, the efficiency up to 95% (step-up ratio is smaller, the output current is smaller, the efficiency is higher), with 3mm fixed screw holes.To ensure the booster efficiency, the maximum boost ratio should be less than 4 (for example, when output 20V, the input should at least be greater than 5V, otherwise the output current and the boost efficiency will be greatly reduced), and the output voltage needs only to adjust the potentiometer on the board.Module parameters:1. Module name: boost module2. Module size: 45 x 20 x 18mm (including the highest electronic component)3. Module properties: non isolated DC-DC boost switching power supply, switching frequency 300KHz4. Input voltage: 3-25V, IN+ input positive, IN- input negative5. Output voltage: 5-25V, default is 12V, OUT+ output positive, OUT- output negative6. Rated input current: 3A7. Output parameters: the safe and stable working output power is best used within 30W (maximum can be as large as 50W when tested and input is 3A and boost ratio less than 4). The test data is shown in the table below.8. Conversion efficiency: 95% MAX (the higher the boost ratio, the higher the efficiency)9. Output ripple: 200mV (MAX)10. Working temperature: industrial grade (-40℃ to +85℃)11. The module has no input reverse connection guarantee. Please b
