As you may know the Power Always voltages, which are always and constantly present on circuits, are very important voltages in circuits.
In this video which is the second part of reading and understanding schematics, we are going to analyze power always voltages 3.3v, 5v, 1.8v and 1v ALW_PWR (power always).
We will also explain and analyze the components that provide these voltage: PU401 (3 volt), PU402 (5 volt), PU601 (1.8 volt) PU601 (1 volt) and analyze all their pins and their obligations in circuit.

Thanks for the explanation !. Intriguing concept on the BYP ( Bypass ) pins at the end of the video, maybe you guys can make a more "in depth" video about that ? Like why, how it works and what possible cause, when the BYP signal is not present.
