Nikolai Posted March 9, 2005 Report Share Posted March 9, 2005 Hi!I just got hold of some switching PSU. Got it to work, buy putting a Led and a resistor on the 5 V and some laps on the 12 V.The only problem is the 5 volt output gives me 5,35. Stupid. Do you think this will drop when it gets more load? 5.35 is not enough to run it trough the 7805 but I guess too much to go directly to the core. Since the same psu has quite a bit of ripple to, I was wondering if anyone has found (and tested) a replacement for the Fortron psu mentioned in the Switching pdf?Sorry for all my psu postsThank you Nikolai Quote Link to comment Share on other sites More sharing options...
moebius Posted March 9, 2005 Report Share Posted March 9, 2005 Hi,Even if voltage doesn't drop with more load on PSU - I'd say 5,35 is still ok for powering Midibox: PIC is rated for MAX 5,5v and HC logic for MAX 6V supply voltages.I hope that PS bypass cap helps to fight ripple issues..Bye, Moebius Quote Link to comment Share on other sites More sharing options...
