ماژول افزاینده DC به DC دارای خروجی 5 ولت

مناسب برای باتری های لیتیومی

نشانگر کاهش ولتاژ ورودی کمتر از 2.7 ولت(در ولتاژهای کمتر led خاموش میگردد)

1-Output current is extended to rated 1A
2- the use of new program design, circuit design does not require electrolytic capacitors and tantalum capacitors (electrolytic capacitor life is short, tantalum capacitors have the risk of explosion) . Using the current high-end circuit on the use of ceramic capacitors (MCC) 3.
Ripple is very low, only a few tens of millivolts, accompanied by a lot of ripple has reached 500 movolts, the equipment will cause an invisible injury, serious equipment will cause abnormal or damage .
3- the  same with the load indicator and undervoltage indication (when the battery voltage is less than 2.7V indicator light in the case of load will be extinguished, when the battery voltage is greater than 2.7V with the load when the indicator light, no load when the light bright)
4- ultra-small size, 14.1 * 18.8 * 5.5 mm
5- circuit conversion efficiency is high, high efficiency when more than 90%, in a single lithium battery efficiency is greater than 80%, unlike the peer some efficiency is only 60-70% efficiency.
6- input low-power reverse polarity protection, if you have a battery with a protective board 2A When you input power positive and negative after the reverse, the protection board will be protected, pay attention when there is no protection board or input current greater than 2A, input reverse protection Will fail, will lead to damage to the module
7- low quiescent current, new version, quiescent current will be less than 100 microamps. There is no need to add a switch to the battery.
With undervoltage indication (input voltage below 2.7V LED off)

Application scope
1) .DIY a mobile power , only need to input a battery in the input, you can output 5V voltage for your phone, MP3, MP4, PSP charge, very simple and convenient Oh.
2). For your electronic equipment power supply , when your device needs 5V power supply, but you now only the hands of lithium battery-powered, with our module can be directly boost to 5V, to solve your problems.
3). The system power supply , when you do a project when the input for the battery-powered (1-5V), and your system board also need 5V stable power, then you choose our module will be your most Good choice, do not have to debug directly on the machine to work, easy to do efficient high-power boost.
Frequently Asked Questions and Answers:
1. Why is my module designed for this shape?
A: Our module is designed for your convenience. You can also remove the USB socket. The module is soldered directly to the PCB and packaged as DIP-24.
2. What is the efficiency of the module work? I used to use the battery above the high efficiency can be used.
A: The efficiency of this module is calculated in the non-synchronous rectification, we can test the efficiency of 96%. There are friends who do not blind pursuit of high efficiency, efficiency is proportional to the price, such as you need 5V 0.5A power supply, 80% efficiency loss of energy 0.625W, 90% efficiency loss of energy 0.278W, Do you think it is necessary to go for this 0.3W power to double the cost of it. Choose a joint on it.
3. Does this power module have short circuit protection? Do I accidentally output a short circuit when I use it.
A: No short circuit protection, if you need short circuit protection, please install the fuse in series at the input.
4. Does this power module have input reverse polarity protection? Do I accidentally enter the power supply when you use it?
A: There is no reverse protection
5. Can this module current run at 5V 500 mA for a long time?
A: The module design power of 2.5W, he can run at 2.5W power for a long time, 5V * 0.5A = 2.5W so it can run for a long time
6. I need about 2A current, this module can work in parallel?
A: The output is directly connected in parallel is not possible, they will form a large circulation between, if you want to output parallel work, you need to put the voltage of each module into a uniform error of less than 50 mV, so you can work, but also Care should be taken to avoid overloading a single module and the output power should not exceed 70% of the total module power.
7. What is the temperature of the working environment of this module and can it reach the industrial level.
A: Yes, the operating temperature is -40 to 85 degrees
