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

Author: Texas Instruments Richard Nowakowski and Brian King 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, First, we first use the Microsoft ide tool vs2005/2008/2010 to build an xaf application.ProgramHere, I use vs2010 to create an xaf winform desktop appli

Cisco CCNA Chapter 4 answers in the second semester, Cisco ccna second semester 1. 2. All the routers running the Distance Vector Routing Protocol have disconnected all power supplies (including spare batteries ). What happens when these routers are reloaded? They share all route information stored in NVRAM before the power-off with the directly connected neighbor

queue, causing a continuous window redraw. CPaintDC can only be used in WM_PAINT message processing. 2 CClientDC classthe CClientDC class is also a derived class of the CDC class. 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

Cisco CCNA Chapter 2 answers for the third semester, Cisco ccna for the third semester 1. Which command line interface (CLI) mode allows users to configure switch parameters such as host name and password? User Execution Mode Privileged Execution Mode Global Configuration Mode Interface Configuration Mode 2.

First, the principle of DC circuit (1) Buck type converter 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 Reduction can be obtained inducta

Differences between LVS and DC-DC Devices 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
