PMIC, Power Management IC---Power Management IC. As the title says, this article will give you a talk about PMIC simulation and how it can help engineers quickly check circuits. I believe that everyone, whether they are doing graduation design or doing some IC design, will know several simulation software with large market share, INSpice, SPICE, Saber, PSpice and so on. These simulation softwares are supported by different user groups due to their simulation quality, simulation efficiency and simulation perfection. However, due to their excellent perfection, they have a huge database, we have to download a larger package to adapt to the latest circuit design. For PMIC designers, this is the most headache, because as an engineer, you have very clear product goals, functional design, for consumer electronics, or medical electronics, but the above software Because the field is too broad, it often wastes a lot of time while getting good data. As a simulation driver for Power Supply design, I hope that there will be convenient and fast simulation software, such as online simulation software or software with only a few megabytes. This kind of software allows us to quickly locate the products we need to know, or to quickly troubleshoot our circuit problems, so that we don't have to worry about the computer can not withstand the excessive program of the software and suddenly crash. Of course, there must be something wrong with it. Similar to this kind of online design software, you can't get the most complete report, but you can get the report you need most. A few days ago, I searched for similar small simulation software on the Internet, and there are very few excellent products. Several companies that are well-known for power management chips have different degrees of cooperation with several simulation products mentioned above. One of the things I noticed is Fujitsu Semiconductor's online design simulator Easy DesignSimTM, which everyone may have noticed its "online" word. Recently, in order to reduce the selection time of peripheral components, more and more products have adopted a method of integrating peripheral components. For example, a voltage setting resistor, a MOS FET, or the like is built into the power chip. Of course, in order to facilitate power supply design engineers to select components, this easy-to-use online simulation environment provided by chip manufacturers makes power supply design easier. Do not know how the specific effect, first register, see the effect. Logging in to register Brabla, it is relatively simple, everyone knows the mail registration, the mailbox is the most important; the next are more programmatic, and similar to other software. Next is the search and selection section, you can set the input voltage, output voltage and load current required by each DC-DC converter; channel settings, click "output n"; set the number of LDO channels. Then select the product, the product has the latest data manual on the left, more humane, if you can not remember, you can also open it, anyway, according to personal intentions, these work is still very easy. Of course, don't forget to set the operating parameters. Step by step, it feels relatively smooth. The input voltage, output voltage, output current, and switching frequency are basic settings. If you need mode selection, you should pay attention to the following PFM/PWM automatic switching. Or PWM fixed, etc., the basic operating parameters are like this, if you need to modify, then call back this page modification. Finally click on the "Create Design" at the bottom! Featuring level VI energy efficiency and meet global safety certifications, the external ac to dc power adapters are available in variety of international different AC input blade versions for United States, Europe, Korea, U.K. and Australia, and provides 8 safety protections. The 12 wattage series wall mount power adapters follows the PC flame retardant plastic case and 3 years warranty.
