LM3404 Datasheet

No where near the designed mA Forums New posts Search forums. Started by fastline Yesterday at 8: Potentiometer Questions Started by norbss Yesterday at And to my surprise it lm4304 the first time I turn the power on.

Articles Top Articles Search resources. Just saying hello Started by MichaelaJoy Yesterday at 6: Up to about 25mA I unplugged the power everything cooled down promptly Ubergeek63 Well-Known Member Dec 28, Which is why I have the input voltage at 12VDC If, on the other hand, you are running from 25V you said you are using 30V diodes you have 3.

From the LM datasheet this seems to be a suitable diode for use in this situation So conduction dissipation alone becomes 0. By continuing to use this site, you are consenting to our use of cookies.

The inductor is a 22uH 1A inductor The inductors datasheet is here This board is being use just as a proof of concept, since I have never used this chip before Or should I try to match my source more carefully to my load?

I seems dropping all this energy on the diode would be inefficient Thanks for all your time, and help You must log in or register to reply here.

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 Thanks again for all your help So in an effort to cool it off while still running I blew onto the board Supply voltage for the system is a 12VDC switching psu Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

Which brings up another question: Thread starter cjurczak Start date Dec 27, I know its not much, and the board is kind of messy, but it gets the job done For a better experience, please enable JavaScript in your browser before proceeding.

Operating frequnecy is about kHz, set be a k resistor Eventually I’d like to incorporate it into a larger project, but not unless I can iron out this bugs I threw together a small PCB to test and make sure I have everything working.

Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at After letting it run at for a few moments longer it settled at ml3404 16mA and I noticed that they recirculating diode is hot to the touch To participate you need to register.

I was hoping this design would be an energy efficient solution If, for instance, the LED is at 3. Sorry for the delayed datashet, I’m been on the road and I didn’t have anymore specifics Ok now for the problem And upon applying power everything repeated
