You can find the Socket component in the Miscellaneous Connectors.IntLib library file. This is essentially a pad that is used to connect to the power supply (see the 12V, GND, and DIM sockets). Although not components per se, there are three Socket connectors that will appear in the schematic.

2 TPS2549 USB switches (1 for each connector)Īll components are surface-mount components.

1 iron-core inductor (used in the buck converter feedback loop), 13 resistors, 19 capacitors.

LM73606 buck converter: used to step-down the 12 V input.

In this project I have the following list of parts: Here, I’m going to show everything in a single schematic as the part count is not terribly large. To get started with the schematic, you’ll need to start with a parts list and think about whether you’ll have to arrange parts in a single schematic or in multiple schematics. This design will feature 2 USB charging ports with LEDs as indicator lights. This board is electrically simple enough that it can be routed on a 2-layer or 4-layer standard thickness board (1.57 mm), but it still requires some important considerations in the schematic and routing portions of the design.

We’ll take a look at the process for creating the schematic first, and the layout process will be shown in an upcoming article. The charger requires 12 V of power and charges two external devices through two USB ports. Here, I’ll present the overall design process for a portable USB charger. If you want to build your own USB charger, you can create your own USB charger board with the powerful schematic design and layout tools in Altium Designer. When I’m in my office, I keep my pluggable USB charger around, otherwise the battery on my phone is likely to run out.
