I'm working on a circuit using the Diodes Inc./Anachip AP1603 boost regulator.
The datasheet (linked above) notes:
Start-up voltage operation is guaranteed with the addition of a Schottky 1N5819 external diode between the input and output.
I'm slightly unclear as to where this should be placed (it's not shown in the sample schematics). Should it be like this:
Or like this:
Side question: Any harm in using ceramic 47µf caps instead of electrolytic or Tantalum ones?
