I arbitrarily decide to use a K ohm resistor for R2 so I just need to do some algebra to determine what R1 must be:. We Supply, You Satisfy!
Follow Blog via Email 30463 your email address to follow this blog and receive notifications of new posts by email. High Voltage Ringer — This is the original post I stumbled across that gives a rough picture of the IC and a decent schematic of its use. Ipk — the peak input current should be mA. Jan 22 update: The chip runs at a max of MHz, so that is what I use.
July 26, at 6: R — This resistor should be ohms. July 26, at But I recently found these cheap little adapter boards 3403 amazon that can be found in a variety of IC packages for example https: January 25, at 9: How to Build a Switch Mode Power Supply Circuit with an MC — Great tutorial and really helped me calculate the passive values by hand though his examples were vague in a few places. L min is 72uH.
5V to 48V Switch-Mode Power Supply using MC | Big Dan the Blogging Man
By continuing to use this website, you agree to their use. Fmin — the minimum frequency.
December 13, at Iout — this is the output current. Using these requirements, according ocl the calculator, the passive values should be: I spent a ridiculous amount of time trying to get an inverting boost power supply working to provide V. Email required Address never made public.
It explains everything, better than I can. You are commenting using your Twitter account. I am building a boost circuit, so the overall circuit layout will look like this:.
Customers who bought this product also purchased Using the worksheet found in the TI datasheet, here are my calculations.
20pcs MC34063 SMD IC
So, where is the 5V coming from? If bad quality issues can be proved, please return the original package within 5 days.
This entry was posted in c-electronics and tagged SMPS. December 13, at 8: Submit a Request Knowledgebase. I want 25mA note that the input current will be much higher than the output current when stepping up this far — in my final 30463, it takes mA 5V to generate 25mA 48V. January 16, at Feedback resistors are chosen from standard component values so that the output is as close to desired value as possible.
My ixl interrogates caller ID while the handset is disconnected. Leave idl Reply Cancel reply Enter your comment here The telco side has only 2 SSRs transferring control of the handset between myself and the telco and a device already certified to provide CID.

I am rather much limited with using through-hole components since the rest of the project is being built that way. Theory and Applications — quite useful for understanding all the various ways the IC can be used.
Finding through-hole packages in nowadays is very hard.
