DC-DC LTC1871 Rate Plipping Power Module high power 100W can be output of 3.5 ~ 35V.

1. Product introduction:

The display part uses a more advanced voltage meter microprocessor, and the voltage part uses the US original imported voltage voltage controller. By using the power MOSFET's informal resistance to save the current detection resistance, the efficiency is improved to the maximum extent.96.4%.Imported high -power low -resistance MOS tube, large packaging, large current, high -efficiency Schutki, ultra -wide and thick PCB wiring, is the guarantee of high -power high -efficiency low temperature rise.Ultra -width voltage work, when the input and output voltage can reach 128W output power above 20V.Long life switching power supply Special high -frequency, high -capacity, low -resistance (low ESR) aluminum electrolytic capacitance makes the output ripple lower.The chips used in the module are imported with original, full of materials and stable performance.

This module was three months old by the team's senior engineer team, and a more intelligent, humanized, and cost -effective module developed.

New advantage function:

1. Land LED working indicators, the working status is more intuitive.

2. One -click switch to the digital tube light, and the measurement of the input output voltage with one click.(The plate voltage indicator "IN" lights the input voltage, and the "out" lights the output voltage).

3. This product is strongly launched, and the voltage display value program is self -reliant function!There will never be a problem of not accurate voltage gauge.

Double -key combination correction voltage method:

Output voltage display calibration

Step 1. Adjust the right -click to turn the "OUT" indicator light. At this time, the voltage table displays the output voltage; long press and right -click 2s and then release.Essence

Step 2, short press (normal speed) right -click, add the voltage value of the voltage value upward; short -click, reduce the voltage value of the voltage value down one unit; because the voltage value of a unit is less than 0.1VThe minimum display of the voltage gauge to 0.1V, so you need to press 1-5 times in a row to see the voltage meter change by 0.1V. The specific key voltage meter changes to 0.1V in a row, depending on the current display voltage. The current display voltage is displayed.The higher, the less the number of movements.

Step 3. After the output voltage is adjusted, long press the right button of the right side of 2s and then release, and you can exit the output voltage to display the calibration mode.All parameter settings are automatically powered off.

Input voltage display calibration

Step 1. Adjust the right -click to turn the "IN" indicator light. At this time, the voltage table displays the input voltage; long press and right -click 2s and then release.Essence

Step 2 and 3 are consistent with the calibration method of the output voltage.

The product has been tested three times before delivery. The voltage display accuracy is guaranteed within 0.1V. The calibration function is designed to meet your higher accuracy requirements. Please use it with confidence.

2. Performance parameters:

1. Input voltage: 3 ～ 35V DC (Note: input voltage is less than 4V, and the plate voltage meter fails)

2. Input current: 9A (MAX)

3、输出电压：3.5～35V直流(此板是升压板，输出电压要>= Input voltage)

4. Output current: 6A (MAX)

5. Output power: 75W, (when the input output voltage is greater than 20V, it can reach 128W)

6. Converting efficiency: 96.7%(the highest)

7. Output lines: 24mv (TYP)

8. The voltage range of the board: 4 ~ 40V, error+-0.1v

9. Short -circuit protection: there are (limited current 14A).Reminder: When connecting high -power loads, because the impact current just turned on, it will limit the self -lock protection. It is recommended to turn on and then connect to the load.

10. Enter anti -connection protection: None (if you need to enter a large current diode in the input).

11. Long x wide x height = 67*43*12mm (excluding copper columns)

Third, the scope of application:

1. DIY a voltage voltage power supply, input 5V, the output can be adjusted at 5-35V.

2. Power on your electronic device, you can set the output value according to your system voltage.For example, 3.7V lithium battery lifts 5V for mobile power, 7.4V or 12V liters of 19 to notebooks.

3. As a power supply power supply, power for your laptop, PDA or various digital products.
