mvs sarma Posted December 9, 2006 Report Share Posted December 9, 2006 Hiplease elaborate your point-- not able to catch it-- you mean deriiving 12v from usb power supply (5V0 for your use in the circuitry used by u.?if so you may use any Dc-Dc converter ( for eg., MC 34023A in the boost mode.with few extra components and convert it to 12v for your use. Is this what you are trying to ask please!! Quote Link to comment Share on other sites More sharing options...
MP Posted December 10, 2006 Report Share Posted December 10, 2006 depends on the current needed and if the DC-DC converter can provide it.MP Quote Link to comment Share on other sites More sharing options...
Ldanielrosa Posted December 25, 2006 Report Share Posted December 25, 2006 Under perfect conditions, trying to get morethan 208mA will exceed USB spec. If you can get 160mA you are doing well. Quote Link to comment Share on other sites More sharing options...
