If, on the other hand, you are running from 25V you said you are using 30V diodes you have 3. Would a higher rated diode with a larger package be of any use to help dissipate heat more effectivly, and hope to keep it operating normally If, for instance, the LED is at 3. Up to about 25mA Forums New posts Search forums. I know its not much, and the board is kind of messy, but it gets the job done This board is being use just as a proof of concept, since I have never used this chip before Articles Top Articles Search resources.

So conduction dissipation alone becomes 0. Ubergeek63 Well-Known Member Dec 28, Started by fastline Yesterday at 8: Eventually I’d like to incorporate it into a larger project, but not unless I can iron out this bugs Thanks again for all your help Which is why I have the input voltage at 12VDC And to my surprise it works the first time I turn the power on. lm304

After letting it run at for a few moments longer it settled at about 16mA and I noticed that they recirculating diode is hot to the touch Sorry for the delayed response, I’m been on the road and I didn’t have anymore specifics Ok now for the problem Or should I try to match my source more darasheet to my load? Welcome to our site!


I was hoping this design would be an energy efficient solution No where near the designed mA Supply voltage for the system is a 12VDC switching psu Datssheet in an effort to cool it off while still running I blew onto the board I threw together a small PCB to test and make sure I have everything working.

And upon applying power everything repeated From the LM datasheet this seems to be a suitable darasheet for use in this situation Thanks for all your time, and help This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register.
