Operating frequnecy is about kHz, set be a k resistor No where near the designed mA Thread starter cjurczak Start date Dec 27, dataheet Ubergeek63 Well-Known Member Dec 28, So in an effort to cool it off while still running I blew onto the board I unplugged the power everything cooled down promptly Welcome to our site! I’d appreciate any comments or previous experience on this topic After letting it run at for a few moments longer it settled at about 16mA and I noticed lm4304 they recirculating diode is hot to the touch Forums New posts Search forums.
I know its not much, and the board is kind of messy, but it gets the job done Thanks again for all your help So conduction dissipation alone becomes 0. Just saying hello Started by MichaelaJoy Yesterday at 6: Potentiometer Questions Started by norbss Yesterday at 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 This board is being use just as a proof of concept, since I have never used this chip before Sorry for the delayed response, I’m been on the road and I didn’t have anymore specifics Articles Top Articles Search resources.
If, for instance, the LED is at 3.
If, on the other hand, you are running from 25V you said you are using 30V diodes you have 3. Eventually I’d like to incorporate it into a larger project, but not unless I can iron out this bugs Started datasheett fastline Yesterday at 8: Or should I try to match my source more carefully to my load?
Supply voltage for the system is a 12VDC switching psu To participate you need to register.
I seems dropping all this energy on the diode would be inefficient And to my surprise it works the first time I turn the power on. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.
Thanks for all your time, and help The inductor is a 22uH 1A inductor The inductors datasheet is here Media New media New comments Search media. Which brings up another question: Click here to register now. Which is why I have the input voltage at 12VDC Up to about 25mA Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at You must log in or register to reply datasehet.
Ok now for the problem And upon applying power everything repeated
