I'm drawing up a circuit using the LM2682 doubling inverter, and the datasheet shows using 3.3uF solid tant capacitors, which are polarized.
The vendor I like to buy from is kinda pricey on solid tant and I already have 4.7uf ceramics on order for another project, so I was hoping I could use those? The datasheet claims larger caps are fine, the caveat is increased design space and cost, with the benefit being lower ripple and internal resistance.
My question; I know it's not good to put polarized caps in where non-polar is specified, but is the reverse also true?
