arsal_uet Posted December 17, 2006 Report Share Posted December 17, 2006 is there any ic which can give me a constant level of voltage even two volts or in other words is ther any ic which give a regulated DC voltage of 2 or 1.7 volts volts for the varrying 1.23 to 1.5 volts.

mvs sarma Posted December 17, 2006 Report Share Posted December 17, 2006 Hi, if it is fast varrying, try a votage doubler with germanium diodes like OA79, etc, the output can be clamped by three silicon diodes to fgive you around 3XVf of the diodes. this provided the variation is equal at MIN and MX. otherwiase try MAX1724. it is said of capable of working from 0.8V.

arsal_uet Posted December 17, 2006 Author Report Share Posted December 17, 2006 but how can i get a constant dc level of 5 volts. Quote Link to comment Share on other sites More sharing options...
mvs sarma Posted December 18, 2006 Report Share Posted December 18, 2006 Hi,when you get a rectified dc, though varrying, the DC content is taken by the ic and the variation is treated as source or supply variation. still the control loop of the ic should give you a regulated o/p for obviously minimal load requirements.
