We do not need to introduce the importance of DC converter in circuit design. Its main function is to convert the voltage into a fixed and effective voltage based on different functions,DC-DCConverter also has a variety of categories. Its main application fields are distributed in digital cameras and mobile phone portable products. A large amount of use makes some common problems in the

The benefit of increasing the switching frequency is obvious, but there are some shortcomings, designers should understand the pros and cons, in order to choose the most suitable switching frequency to be applied. This practical article will explain these considerations one by one.
DC power converters with high switching frequencies are becoming popular because they can save board space with
PreviousArticleI introduced the DC and introduced the official description and features of the DC. At the beginning, I will start with the actualCodeProject to gradually introduce a DC-based procurement system,

It can only be plotted in the client area of the window (that is, in the window except for the border, the title bar, the menu bar, and the middle part of the status bar), the coordinate point (0,0) usually refers to the upper-left corner of the customer area. Its constructor calls the GEGDC function, and the destruct

Dcdc means DC to DC (to) DC (conversion of different DC power supply values), as long as it complies with this definition, it can be called dcdc converter, including ldos. However, the g

Brief analysis: During the opening of the switching tube s, the current is charged to the capacitance C through the switch tube and inductance.
When the switching tube s is off, the filter capacitance C is charged to r, because the inductor current cannot be mutated, through the RC circuit, D discharge
Brief calculation:
When the switch tube is on, there is

It includes boost, Buck, boost, Buck, and reverse structures, featuring high efficiency, high output current, and low static current. The disadvantage of this type of power supply controller is that the Output Ripple and switch noise are large, and the cost is relatively high.

The power ripple index of the DC/DC module is an important parameter. A clean power supply is a prerequisite for the stable operation of the digital circuit and an important guarantee for the parameters of the simulator. To determine the power quality, the Output Ripple of the DC/DC module must be measured. However, th
Can the IP address and computer name of the DC be changed arbitrarily? The answer is certainly not. Here's how to change the IP and computer name of a DC.One. Change the domain controller IP address.

Build an eclipse Android Development Environment (eclipse + jdk + adt + sdk) and Android adt
The school's summer job allows android to write an app. There are two solutions (android stduio + sdk and eclipse + jdk + adt + sdk). After a few days, I found that the latter is easy to use, however, the installation environment and downloading are really just half-lived
Yesterday hand the Android SDK upgrade, and then get the ADT version does not correspond, and then search from the Internet some methods ~ effect can also, reinstall ADT.The method for uninstalling ADT is as follows (my eclipse version is 3.5):1.

When Eclipse creates an Android project, you are prompted when previewing the Layout.xml file: This version of the rendering library was more recent than your version of ADT plug- In. Please update ADT plug-in, resulting in the inability to preview the layout file properly. Root cause: The SDK version is too high and the ADT version is too low. The workaround is
After the ADT is installed, the SDK will be updated as well. Later, I want to see what version I upgraded. It turns out that there is a small robot icon in eclipse's help-> about eclipse, which is the android open source project. Click it and you will see its version. My current version is 0.9.7. Complete this process ~~~
If ADT releases a new version, how can we upgrade it? Generally, you can download fi
