Hi all, 

Chip long time no post anything interesting, is to learn the IC mc34063, to earn share posts made redundant charging circuit for Smartphone Post to share your research and learn, how people do How? 

Do not by Chip circuit design should not ensure stability chay.Chip not resolve complaints when the circuit xoet xoet offline ^^

I. Charging circuit diagram mc34063 Step up 

Surely many of you see the status of the battery for Smart Phone. In this symposium to share their phone charger circuit can pocket for your phone. I wish you well done it this circuit .... 

Summary: 

Battery power circuit: Lion Battery, cell laptop batteries, or simply your phone. 
Charging Connectors: USB 
Compatibility: Android, Windows Phone, iOS devices .... support charging via USB port (in addition to the user terminal connector jack like Nokia ....) 
Performance: 85%

PCB 

Temporary no real image damaged by the 1202 Orange circuit and I was doing very well used. 

See how to calculate these parameters: http://www.nomad.ee/micros/mc34063a/ 

According Mobileworld.vn 

II. Create backup Battery Charger 

a.Chuan be material: 
1: One or two phone battery is not in use. 
2: A car charger jack fit your phone (about $ 20k / local) for wireless components and take charge jack, one set is almost always enough components (Prepare purchase right price 20k / real instruments) 
3: A cell phone batteries old broken (for parts only, on the other battery then off to.) 
4: LED, IC TL431, tape, lead-free solder .di course ...... 

First b.Bat fight ^^ 

Step 1: Make cell circuit protection: 
Battery backup is here selected cell laptop battery has a nominal voltage of 3.7V, 2500mAh capacity over a lump. You can use one or two offices, if a simple backup, only one department is enough. Here viethung94 using 2 cell connected in parallel. Because cell battery will be damaged when the load required for cell battery protection circuit. Simple and especially your standard battery for an old broken phone, extract cell protection circuit components such as circuit protection we have cell was switched off at full load (4.2V), short-break when the first out, automatically disconnect the load cell voltage is too low to limit the voltage (2.5V) for cell protection. Picture the protection circuit like this, sir: 




cover close enough room 2 

Cell-cell and circuit protection. 
This step was done with a full battery. 

Step 2: Charging the battery backup circuit. 
After you have completed the cell and circuit protection, we make backup battery charger circuit. Charger circuit diagram as follows: 



When the battery backup of all, I always use a small vacuum charger (2mm) NOKIA common to recharge. We store the components phone charger buy male foot of the machine as 3110c, 1280 in use. In the circuit using IC TL431 is a controlled zene to indicate battery. When the battery is not full, charging voltage of 2 feet less than 5V, TL431 certainly not common, LED lit when the battery is full and charging protection circuit breaker onto the 5V voltage (optional charger can to 7V) TL431 is fully informed and led glowing report tells us that the battery is full. 

Step 3: Make bost circuit voltage from the battery voltage to charge the phone. 
The circuit uses IC mc34063 very simple, less components and easy success. The diagram is as follows: 


Notes: 
Diagram drawing lacks mass, mass general C1 capacitor connected to the negative (vacuum 4IC) 
Cored inductors in the circuit all the way from the old motherboard to remove the old wire coils wrapped around age 20 is 0.4mm. If you do prepare automobile charger as I said from the beginning of this charger had enough of all components, only missing tran D965. 

Step 4: Put the ingredients together 
Once you've assembled the charging circuit, the circuit bost connect them according to the scheme after one complete backup battery 

The output of the wire used is always available on the phone jack on the car charger circuit, this wire is very compact and convenient. 

The final product after the completion of e are here

    Some chargers hire a trickle charge, supplying only a little bit of current that will take many hours to charge a cell, whilst others may charge batteries inside of one hour.

Using the TLP250 Isolated MOSFET Driver - Explanation and Example Circuits

I’ve already shown how to drive an N-channel MOSFET (or even an IGBT) in both high-side and low-side configurations in a multitude of ways. I’ve also explained the principles of driving the MOSFETs in these configurations. The dedicated drivers I’ve shown so far are the TC427 and IR2110. Some people have requested me to write up on MOSFET drive using the very popular TLP250. And I’ll explain that here. The TLP250, like any driver, has an input stage, an output stage and a power supply connection. What’s special about the TLP250 is that the TLP250 is an optically isolated driver, meaning that the input and output are “optically isolated”. The isolation is optical – the input stage is an LED and the receiving output stage is light sensitive (think “photodetector”). Before delving any further, let’s look at the pin configuration and the truth table. Fig. 1 - TLP250 Pin Configuration Fig. 2 - TLP250 Truth Table Fig. 1 clearly shows the input LED side and the receiving photodetector as well

N-Channel MOSFET High-Side Drive: When, Why and How?

I had previously shown how to drive N-channel MOSFETs in low-side configuration. You can find the tutorial here: http://electel.blogspot.com/2016/12/low-side-mosfet-drive-circuits-and_23.html I’ve been requested to write a tutorial/article regarding high-side MOSFET drive. So, here I’ll talk about N-channel MOSFET high-side drive. Let’s first look at the common low side configuration.  Fig. 1 - N-channel MOSFET configured as low-side switch Now let’s look at a MOSFET configured as a high-side switch. Fig. 2 - N-channel MOSFET configured as high-side switch You can quite easily see the difference between the high-side configuration and the low-side configuration. In the low-side configuration, the load is connected between the drain and +V, while the source is connected to ground. Thus, the gate drive is referenced to ground. So by applying a voltage of >7V (for Power MOSFETs) or >4V (for Logic Level MOSFETs), the MOSFET can be fully turned on. Now let’s talk about the high-side c

Using the high-low side driver IR2110 - explanation and plenty of example circuits

-

In many situations, we need to use MOSFETs configured as high-side switches. Many a times we need to use MOSFETs configured as high-side and low-side switches. Such as in bridge circuits. In half-bridge circuits, we have 1 high-side MOSFET and 1 low-side MOSFET. In full-bridge circuits we have 2 high-side MOSFETs and 2 low-side MOSFETs. In such situations, there is a need to use high-side drive circuitry alongside low-side drive circuitry. The most common way of driving MOSFETs in such cases is to use high-low side MOSFET drivers. Undoubtedly, the most popular such driver chip is the IR2110. And in this article/tutorial, I will talk about the IR2110. You can download the IR2110 datasheet from the IR website. Here's the download link: www.irf.com/product-info/datasheets/data/ir2110.pdf First let’s take a look at the block diagram and the pin assignments and pin definitions (also called lead assignments and lead definitions): Fig. 1 - IR2110 block diagram (click on image to enlarge)
