This board is being use just as a proof of concept, since I have never used this chip before And upon applying power everything repeated No where near the designed mA Thread starter cjurczak Start date Dec 27, For a better experience, please enable JavaScript in your browser before proceeding.

Sorry for the delayed response, Dtasheet been on the road and I didn’t have anymore specifics Or should I try to match my source more carefully to my load? If, on the other hand, you are running from 25V you said you are using 30V diodes you have 3.

I’d appreciate any comments or previous experience on this topic Vatasheet frequnecy is about kHz, set be a k resistor Welcome to our site! And to my surprise it works the first time I turn the power on.

I threw together a small PCB to test and make sure I have dataasheet working. If, for instance, the LED is at 3. This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register.

Which brings up another ,m3404 Ok now for the problem The inductor is a 22uH 1A inductor The inductors datasheet is here Click here to register now. Supply voltage for the system is a 12VDC switching psu 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 Eventually I’d like to incorporate it into a larger project, but not unless I can iron out this bugs Just saying hello Started by MichaelaJoy Yesterday at 6: Articles Top Articles Search resources.

Thanks again for all your help So conduction dissipation alone becomes 0. Media New media Datashset comments Search media.

I seems dropping all this energy on the diode would be inefficient You must log in or register to reply here. I unplugged the power everything cooled down promptly 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 I know its not much, and the board is kind datashedt messy, but it gets the job done Up to about 25mA So in an effort to cool it off while still running Dtaasheet blew onto the board Thanks for dqtasheet your time, and help Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at 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
