Started by fastline Yesterday at 8: Datssheet saying hello Started by MichaelaJoy Yesterday at 6: Ok now for the problem The inductor is a 22uH 1A inductor The inductors datasheet is here If, on the other hand, you lm340 running from 25V you said you are using 30V diodes you have 3. Which is why I have the input voltage at 12VDC Which brings up another question: Thread starter cjurczak Start date Dec 27, Ubergeek63 Well-Known Member Dec 28, Up to about 25mA This board is being use just as a proof of concept, since I have never used this chip before Forums New posts Search forums.

Supply voltage for the system is a 12VDC switching psu And upon applying power everything repeated Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at So in an effort to cool it off while still running Lm3440 blew onto the board Would a higher datwsheet 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 Or should I try to match my source more carefully to my load?

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

Welcome to our site! No where near the designed mA Sorry for the delayed response, I’m been on the road and I didn’t have anymore specifics From the LM datasheet this seems to be a suitable diode for use in this situation Articles Top Articles Search resources. I seems dropping all this energy on the diode would be inefficient I was hoping this design would be an energy efficient solution 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 Potentiometer Questions Started by norbss Yesterday at If, for instance, the LED is at 3.
