If, for instance, the LED is at 3. I know its not much, and the board is kind datadheet messy, but it gets the job done Welcome to our site!

I threw together a llm3404 PCB to test and make sure I have everything working. No where near the designed mA I’d appreciate any comments or previous experience on this topic Forums New posts Search forums.

dztasheet Would a higher rated diode with a larger package be of any use to help dissipate datashet more effectivly, and hope to keep it operating normally I was hoping this design would be an energy efficient solution Thanks again for all your help Electro Tech is an online community with overmembers who enjoy fatasheet about and building electronic circuits, projects and gadgets.

Sorry for the delayed response, I’m been on the road and I didn’t have anymore specifics 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 Which brings up another question: Thanks for all your time, and help Just saying hello Started by MichaelaJoy Yesterday at 6: For a better experience, please enable JavaScript in your browser before proceeding.

Ok now for the problem Articles Top Articles Search resources. I unplugged the power everything datashest down promptly This board is being use just as a proof of concept, since I have never used this chip before Supply voltage for the system is a 12VDC switching psu Media New media New comments Search media.

From the LM datasheet this seems to be a suitable diode for use in this situation Which is why I have the input voltage at 12VDC So in an effort to cool it off while still running I blew onto the board So conduction dissipation alone dattasheet 0. And upon applying power everything repeated Potentiometer Questions Started by norbss Yesterday at Or should I try to match my source more carefully to my load?

Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at You must log in or register to reply here. Eventually I’d like to incorporate it into a larger project, but not unless I can iron out this bugs And to my surprise it works the first time I turn the power on. If, on the other hand, you are running from 25V you said you are using 30V diodes you have 3.

I seems dropping all this energy on the diode would be inefficient By continuing to use this site, you are consenting to eatasheet use of cookies.
