When novices design PCBs, they usually place the devices as they wish when the circuits are reasonable. If you say it cannot be used, it can still be used. If you say it can be used, the expected effect cannot be achieved in some cases. For some newly purchased chips, newcomers often cannot master all the details of it. They always find out that some areas need improvement after getting into the pit. Now there are some very practical PCB layout techniques that you can refer to below.
Taking the power regulator chip as an example, such as the commonly used LM2596-ADJ, first step should search for datasheet from the manufac. web site
The data sheet contains all the information about this chip. It is a tool that electronic engineers should make good use of. There is a lot of information, so you can focus on the key points. In the data sheet, you can scroll down to see the circuit diagram of the chip you want, and there are also specific elements. Device parameter selection, various parameter calculation methods.
Continuing to scroll down, you can even see the layout of the PCB. When a novice designs the PCB, they can place it according to the same parameters and packages. Then, copy the PCB design based on the vias, windows, and trace widths of the schematic diagram, which is almost brainless.
In the same way, not only power chips, but also motor drive, charging management and other chips can also find the corresponding chip layout in the data sheet. for Example BQ24072 Battery charger IC
Some students may find that there are no such PCB layout examples in some data sheets. That is because different chip manufacturers have different data sheet contents. At this time, you can find the data sheets of several manufacturers and drag them to the back to see if there is a layout. case. for example if you plan to work with XH2596-12 ( from Chinese manufac. XINLUDA ) you can try to use the same datasheet of LM2596-12
Finally we hope our presented information be useful and helpful for you , also if you find any wrong or mistakes or any recommended notes you can send us and we will update accordingly
