Hi,
I'm planning on making a small power supply as a project to learn some more about PCB layouts and SMD soldering.
I'm looking at the design example (attached) and have a few questions.
C1 through C5 are all the same, if I can get a single 50uF cap can I use it, or is there a reason to have an array of 5 10uF?
Same question for C11 and C12, except they have two connections drawn to ground instead of one. Is that some kind of specialty capacitor or am I supposed to make the traces extra big or what?
Also, the mosfet they are reccomending has 4 drain pins, but only one of them is shown, while three pins are used on the source. What is the explanation for this?
Thanks.
