Welcome to our site! This board is being use just as a proof of concept, since I have never used this chip before The inductor is a 22uH 1A inductor The inductors datasheet is here Media New media New comments Search media.

And upon applying power everything repeated I know its not much, and the board is kind of messy, but it gets the job done And to my surprise datashret works the first time I turn the power pm3404. Operating frequnecy is about kHz, set be a k resistor No where near the designed mA This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register.

Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at I lm34404 the power everything cooled down promptly For a better experience, please enable JavaScript in your browser before proceeding. Thread starter cjurczak Start date Dec 27, So conduction dissipation alone becomes 0. Sorry for the delayed response, I’m been on the road and I didn’t have anymore specifics I threw together a small PCB to test and make sure I have everything working.

Supply voltage for the system is dayasheet 12VDC switching psu Forums New posts Search forums.

I seems dropping all this energy on the diode would be inefficient If, on the other hand, you are running from 25V you said you are using 30V diodes you have 3. Just saying hello Started by MichaelaJoy Yesterday at 6: I was hoping this design would be an energy efficient solution I’d appreciate any comments or previous experience on this topic If, for instance, the LED is at 3.

Potentiometer Questions Started by norbss Yesterday at From the LM datasheet this seems to be a suitable diode for use in this situation 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 Eventually I’d like to incorporate it into a larger project, but not unless I can iron out this bugs Ok now for the problem Up to about 25mA So in an effort to cool it off while still running I blew onto the board Thanks again for all your help Thanks for all your time, and help Which brings up another question: By continuing to use this site, you are consenting to our use of cookies.
