max232epe gets hot , real hot

[richard]

I was just looking at a schematic for a microchip usb/serial debugger header and noticed they only use 0.1uF caps on pins 2 and 6 (the +- 10v rails) in lieu of the recommended 1.0uF or bigger by the maxim datasheet. tried that, it has improved the charge pump startup to almost 100% .
fingers crossed

ps the max232n seem to switch the caps @19khz the max232epe @640khz they are quite different animals

Seems logical, higher frequency, lower capacity.

I believe this was the problem.
