ماژول رگولاتور DC به DC افزاینده LTC1871

ماژول رگولاتور DC به DC افزاینده LTC1871 دارای نمایشگر و قابلیت تنظیم ولتاژ خروجی

رگولاتور وسیله ای برای تثبیت ولتاژ می باشد و میتواند به دو صورت کاهنده یا افزاینده ولتاژ باشد. در رگولاتور افزاینده مقدار ولتاژ خروجی بیش از ولتاژ ورودی می باشد اما جریان خروجی کمتر از جریان ورودی می باشد.
تراشهLTC1871 به همراه یک نمایشگر سگمنت، هیت سینک، و پتانسیومتر همگی این ماژول افزاینده ولتاژ را تشکیل دادند و امکان نمایش مقدار تنظیم شده خروجی و تغییر ولتاژ با استفاده از مولتی ترن را دارد.
برای تغییر میزان ولتاژ خروجی، کافی ست با استفاده از یک پیچ گوشتی دوسو کوچک، مولتی ترن را تنظیم کنیم.
ماژول رگولاتور DC به DC افزاینده 100 وات LTC1871 دارای طول عمر زیاد، مناسب برای سوییچینگ مدارات فرکانس بالا و ریپل خروجی کم می باشد.
بر روی برد این ماژول، LED تعبیه شده است تا وضعیت کارکرد ماژول را اعلام کند. همچنین دارای ولتاژ سنج برای اندازه گیری دقیق ولتاژ و نمایش آن بر روی سگمنت می باشد.

Description:
A boost converter (step-up converter) is a DC-to-DC power converter that steps up voltage (while stepping down current) from its input (supply) to its output (load). It is a class of switched-mode power supply (SMPS) containing at least two semiconductors (a diode and a transistor) and at least one energy storage element: a capacitor, inductor, or the two in combination. To reduce voltage ripple, filters made of capacitors (sometimes in combination with inductors) are normally added to such a converter's output (load-side filter) and input (supply-side filter).
This converter adopts advanced voltage meter microprocessor, through the use of the power MOSFET on resistance and saves the current detecting resistor, maximizing its efficiency to 96.4%. It features a wide operating supply range with a power supply input voltage between 3.5 to 35V and will step-up this input voltage from 4V to 35V. The module also includes an integrated voltage meter that can measure both the input and output voltages. A voltage selection button allows for easy switching.

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

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 a 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.

Features :
1. Input voltage: 3 ~ 35V DC (Note: the input voltage is less than 4V, the onboard 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. Onboard 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 currently 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 an "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 cutting 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 sent 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.
