I have ordered some lmHV.

January 22, at 2: Make Your Switch Sound Activated In this article, we’ll build a sound-activated switch that can be opened and closed with a double clap. Or at best, it switches off.


Feb 11, 5, 1, But I recently found these cheap little adapter boards on amazon that can be found in a variety of IC packages for example https: Feb 14, Vripple — the voltage ripple in the output.

A few other powdered-iron toroid inductors were tried and it is not that critical. Scope current L1 inductor at 5v 0. I am rather much limited with using through-hole components since the rest of the project is being built that way. I googled and found that a “buck regulator” and a “buck converter” are the same, and WIKI has a nice page on it. July 26, at This site uses cookies.


12v to 5v DC high efficiency SMPS buck converter using 34063 IC.

This is where the calculator comes in. Even the SG that I had initially tried to use is not acceptable either and, if I recall, everything else I looked at was ridiculously expensive if I ever hope to do something commercial with my project. For what it is worth, the 78l05 still makes a good and cheap voltage reference, but the does not have much use nowadays. The filter caps; uF on the input and uF on the output were chosen to be “good enough”.

January 25, at 9: To use the calculator, you are going to need datashert know Vin — this is the minimum input voltage. Modifying the circuit for 12v car operation. July 26, at 6: Posted by Lumenosity in forum: Dec 28, 3.

It has 51 turns of 1. Output ripple was approx mV which is fine. Sep 7, 2, The PFET on period is the top of the waveform.

Dec 29, 7. Determining the Overall Circuit Layout The way the passive components are connected to 34063sp1 MC depend on what type of power supply you are building: This costs significant efficiency. Have you looked at any of the newer SMPS chips with integrated switch?

A properly selected inductor or a good core hand wound for best performance could allow lower operating frequency and less current ripple, and maybe less DC ohms, and maybe pick up another 0.

The IC does all the clever stuff, mainly it regulates voltage at 1.

The SSRs are connected such that if there is no signal from the Teensy, the handset is connected to the telco the N.
