ماژول رگولاتور DC به DC افزاینده 100 وات LTC1871 همراه با نمایشگر ولتاژ

Introduction:
This display part adopts advanced voltage meter microprocessor,boosting part adopts American imported boost controller, through the use of the power MOSFET on resistance and save the current detecting resistor, maximizing it efficiency to 96.4%. Import the big power MOS low resistance pipe, large package, high current, high efficiency Schottky, super wide thickened wire of PCB low temperature rise, high power and high efficiency.Ultra wide working voltage,when the input and output voltage is above 20V it can be up to 128W of output power.Long life type switching power supply special high frequency high capacity and low resistance (low ESR) aluminum electrolytic capacitor to lower output ripple. Module chip used are imported materials, stable performance.
This module is a more intelligent, humane, high cost performance module.

The additional advantage of function:
1. On board LED work indicating lamp, the working state is more intuitive.
2.Switch digital tube lights, switch measuring input and output voltage. (the on board voltage indicator "IN" show input voltage, the "OUT" bright display output voltage).
3.This product has voltage meter automatic calibration function, it will not exist the problem of accurate voltage meter!

Performance parameter:
1.Input voltage: 3 ~ 35V DC (Note: the input voltage is less than 4V, the on board voltage meter failure)
2.Input current: 9A (max)
3.Output voltage: 3.5 ~ 35V DC (this board is a step-up in input voltage, output voltage to > =)
4.Output current: 6A (max)
5.Output power: 75W, (when the input voltage and the output voltage is greater than 20V can reach 128W)
6.Conversion efficiency:96.7% (the highest):
7.Output ripple (TYP): 24mV
8.On board voltage meter range: 4~40V, error +-0.1V
9.Short circuit protection: (current limiting 14A). Warm tip: in the access of large power load, because just start impact current is big and limiting self-locking protection, suggest first boot, then access load.
10.Input reverse connection protection: none (such as the need to please in the input string into the high current diode).
11.Length x width x high =67*43*12MM (excluding the pillars)
This product has the new function of double bond portfolio correction voltage.

Specific methods are as follows:
The output voltage display calibration
Step 1: adjust the right key to make a "OUT" indicator lights, when voltage meter display output voltage; long right-click over 2S after release, voltage meter and the"OUT" indicator synchronous flashing, so you can enter the output voltage display calibration model.
Step 2: short press (normal speed can be) right click a voltage value, voltage added to a unit value; short press the left key, the voltage value of cut down voltage of a unit of value; voltage due to a unit value is less than 0.1V, the minimum voltage meter display to the 0.1V, so you need to continuously press 1-5 to see the change of the voltage meter 0.1V, according to several key specific continuous voltage meter 0.1V changes, depending on the current display voltage, current display voltage is higher,the fewer the number of press.
Step 3: output voltage adjust finished, long press the right buttons above 2S after release, you can exit the output voltage display calibration model. All parameters set to automatically save the power down.
Input voltage display calibration
Step 1: adjust the right key to make a "IN" indicator light, when voltage meter display input voltage; long right-click over 2S after release, voltage meter and the "IN" indicator synchronous flashing, you will enter the input voltage display calibration model.
The output voltage of steps 2 and 3 are in the same display calibration method.
Note: This product has tested more than three times before shipment, voltage display is in the range of 0.1V, the calibration function is to meet your higher accuracy requirements and design, you can use it safely.

Application
1. DIY a power supply,input 5V, output 5-35V can be adjustable.
2. As the power supply of your electronic device, set the output voltage value according to your system. For example 3.7V Lithium Mobile Power 5V as mobile power source, 7.4V or 12V 19 to the laptop power supply.
3. As the car power supply , supply for your laptop, PDA or a variety of digital products.
