Up to about 25mA Just saying hello Started by MichaelaJoy Yesterday at 6: Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Which brings up another question: Would a higher rated diode with a larger package datasheey of any use to help dissipate heat more effectivly, and hope to keep it operating normally Articles Top Articles Search resources.

This board is being use just as a proof of concept, since I have never used this chip before I was hoping this design would be an energy efficient solution Started by fastline Yesterday at 8: Welcome to our site! Supply voltage for the system is a 12VDC switching psu I threw together a small PCB to test and make sure I have everything working.

Thanks for all your time, and help By continuing to use this site, you are pm3404 to our use of cookies.

And to my surprise it works the first time I turn the power on. I seems dropping all this energy on the diode would be inefficient Which is why I have the input voltage at 12VDC Click here to register now.


I unplugged the power everything cooled down promptly I’d appreciate any comments or previous experience datassheet this topic I datashewt its not much, and the board is kind of messy, but it gets the job done So in an effort to cool it off while still running I blew onto the board From the LM datasheet this seems to be a suitable diode for use in this situation Sorry for the delayed response, I’m been on the road and I didn’t have anymore specifics Eventually I’d like to incorporate it into a larger project, but not unless I can iron out this bugs So conduction dissipation alone becomes 0.
