Product introduction:
1. The display part adopts a more advanced voltmeter microprocessor, and the boost part adopts a boost controller imported from the United States. By using the on-resistance of the power MOSFET, the current detection resistor is omitted, which maximizes the efficiency and maximizes the efficiency. Up to 96.4%.
2. Imported high-power low-resistance MOS tube, large package, high current, high-efficiency Schottky, ultra-wide and thick PCB trace, is the guarantee of high-power, high-efficiency and low-temperature rise.
Ultra-wide voltage work, when the input and output voltages are above 20V, it can reach 128W output power.
3. Long-life switching power supply special high-frequency, high-capacity, low-resistance (low ESR) aluminum electrolytic capacitors, so that the output ripple is lower. The chips used in the module are imported with original packaging, full of materials and stable performance.
This module was developed by a team of senior engineers in the studio for three months to develop a more intelligent, humane, and cost-effective module.
New advantages:
1. On-board LED working indicator, the working status is more intuitive.
2. One key to switch the digital tube on and off, one key to switch the input and output voltage measurement. (The onboard voltage indicator "IN" lights up to display the input voltage, and "OUT" lights up to display the output voltage).
3. This product is launched strongly, the voltage display value program self-calibration function! There will never be the problem of inaccurate voltmeters.
Two-key combination correction voltage method:
Output voltage display calibration
step 1:
Adjust the right button to make the "OUT" indicator light, and then the voltmeter displays the output voltage; press and hold the right button for more than 2 seconds and then release, the voltmeter and the "OUT" indicator flash simultaneously, so you enter the output voltage display calibration mode.
Step 2:
Short press the right button once (normal speed is sufficient), the voltage value will increase by one unit of voltage value; short press the left button, the voltage value will decrease by one unit of voltage value; since the voltage value of one unit is less than 0.1V, the voltmeter The minimum display is 0.1V, so you need to press 1-5 times to see that the voltmeter changes by 0.1V. The specific voltage meter changes by 0.1V by pressing the key several times. It depends on the current display voltage. The higher the current display voltage, The fewer presses.
Step 3:
After adjusting the output voltage, press and hold the right button for more than 2 seconds and then release it to exit the output voltage display calibration mode. All parameter settings are automatically saved after power-off.
Input voltage display calibration

Step 2:

The specific voltage meter changes by 0.1V by pressing the key several times. It depends on the current display voltage. The higher the current display voltage, The fewer presses.
Step 3:
After adjusting the output voltage, press and hold the right button for more than 2 seconds and then release it to exit the output voltage display calibration mode. All parameter settings are automatically saved after power-off.
This product has been inspected more than three times before shipment, and the voltage display accuracy is guaranteed to be within 0.1V. The calibration function is designed to meet your higher accuracy requirements. Please rest assured to use it.
2. Performance parameters:
1. Input voltage: 3～35V DC (Note: if the input voltage is less than 4V, the on-board voltmeter is invalid)
2. Input current: 9A (max)
3. Output voltage: 3.5～35V DC (this board is a booster board, and the output voltage must be >=input voltage)
4. Output current: 6A (max)
5. Output power: 75W, (when the input and output voltages are both greater than 20V, it can reach 128W)
6. Conversion efficiency: 96.7% (the highest)
7. Output ripple: 24mV (TYP)
8. Range of onboard voltmeter: 4~40V, error +-0.1V
9. Short circuit protection: Yes (limited current 14A). Reminder: When connecting to a high-power load, the current limiting and self-locking protection will be caused due to the large inrush current at the beginning of the startup. It is recommended to turn on the device first, and then connect to the load.
10. Input reverse connection protection: None (please insert a high-current diode in series with the input if necessary).
11. Length x width x height=67*43*12MM (without copper pillar)
3. Application scope:
1. DIY a regulated power supply, input 5V, output can be adjusted from 5-35V.
2. To supply power to your electronic equipment, you can set the output value according to your system voltage.
For example, a 3.7V lithium battery can be increased to 5V as a mobile power supply, and 7.4V or 12V can be increased by 19 to power a notebook.
3. As a vehicle power supply, power your laptop, PDA or various digital products
