Plastic USB Really Very Convenient, With The Use Of Charge

Mobile phone charging, the use of car vacuum cleaners, are inseparable from the car charger. But often the owner encountered car charger smoke, cigarette lighter was burned, and even the car "fuse" was burned.

How to choose safe and easy to use car charger?

Now the phone's screen is getting bigger and bigger, can listen to songs to navigation, but more electricity, need to charge at any time; serious weather pollution, the car often dust, many owners have their own vacuum cleaner, which are inseparable Car Charger. But how to choose car charger it

At present more and more occasions and equipment equipped with one or more Plastic USB charging port, and car Plastic USB charger is one of the important components. As the body size is larger, the car line longer, Plastic USB charging port voltage may be reduced with the impedance of the line resulting in insufficient charging current.

This paper introduces the design of a car Plastic USB charger with line compensation function, which makes the voltage of Plastic USB charging port increase with the increase of current, thus realizing the constant charging voltage of Plastic USB and ensuring the charging current of Plastic USB port.

DC / DC Buck Converter: The design of the main power stage using the TI LM25117-Q1 control of the synchronous buck converter. The LM25117-Q1 is an automotive grade that provides a variety of protection for power circuits, including adjustable input undervoltage, overcurrent and short circuit, and overtemperature protection.

In addition, the LM25117-Q1 can be analog diode control, through the external settings, making the synchronous buck converter at light load when the analog diode work, in the detection of the reverse tube when the reverse current, turn off the tube, improve the converter light load effectiveness.

Now the use of mobile phones, Tablet PC is very common, in order to solve these digital products charging problems, some drivers friends often installed in the car car charger. Such a small device as long as the car cigarette lighter on the plug, and then need to charge the equipment to the back of the Plastic USB port, you can easily charge up. In addition, many driving recorder and other interior equipment is also through the car charger to power. However, it has recently been suggested that the car charger, although easy to use, the problem is a lot, and may even explode! So, this little car charger, really so insecure?

Car charger referred to car charger, is now a very common car supporting device. However, after entering the summer, the car charger will explode the news began in the circle of friends crazy. Reporters consulted the news, found that Mr. Tang in Xi'an last year encountered such a strange thing.

Fine carved so that the machine seamless stitching, but also with the red LED energy ring.

Independent anti-electromagnetic interference circuit, to avoid a variety of automotive products, electromagnetic frequency pulse interference, even if navigation, radio, speakers and other vehicle equipment can be used at the same time.

Charger end of the shell is a world-class high temperature flame retardant material, even if the scorching sun does not charge hot.

Bilateral stainless steel spring bayonet design, effectively prevent the plug from the cigarette lighter in the slide, durable.

But with it really very convenient, with the use of charge, no matter where you do not have to worry about mobile phone power.
