Click here to register now. 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 I was hoping this design would be an energy efficient solution Thanks for all your time, and help You must log in or register to reply here.

Ok now for the problem Sorry for the delayed response, I’m been on the road and I didn’t have anymore specifics Ubergeek63 Well-Known Member Dec 28, I unplugged the power everything cooled down promptly This board is being use just om3404 a proof of concept, since I have never used this chip before To participate you need to register.


Operating frequnecy is about kHz, set be a k resistor So in an effort to cool it off while still running I blew onto the board Thanks again for all your help Potentiometer Questions Started by norbss Yesterday at By continuing to use this site, you are consenting to our use of cookies. Which brings up another question: Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Up to about 25mA Eventually I’d like to incorporate it into a larger project, but not unless I can iron out this bugs The inductor is a 22uH 1A inductor The inductors datasheet is here Supply voltage for the system is a 12VDC switching psu Forums New posts Search forums.

And to my surprise it works the first time I turn the power on. I threw together a small PCB to test and make sure I have everything working.


LM overview, product comparison and replacement search

Thread starter cjurczak Start date Dec 27, Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Which is why I have the input voltage at 12VDC I seems dropping all this energy on the diode would be inefficient If, for instance, the LED is at 3.

From the LM datasheet this seems to be a suitable diode for use in this situation No where near the designed mA I know its not much, and the board is kind of messy, but it gets the job done Or should I datasehet to match my source more carefully to my load?

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
