This is a simple ORing Board to support the combination of two different power supplies and share the load effeciently between each utilizing the LTC4370 chip. The choice of mosfets and capacitors has to do with the application which is why their is no notation on their values. Instead, the datasheet for ltc4370 outlines the calculations for each capacitor. Also, you may want to change the sense resistors as well. Again, all components are in regards to the application desired by the user. I am ORing two cheap ATX power supplies to create an extra powerful benchtop power supply with many other features. Good Luck.
