LM567 IC Calculator Tool

Last Updated on May 20, 2026 by Swagatam 6 Comments

LM567 application circuit

We can use this small LM567 calculator tool for finding the right frequency, Rt, and Ct values for our tone decoder circuit. Now we know that this IC works on one simple relation which is, f = 1 / (1.1 × Rt × Ct) So we can see that this frequency depends only on the […]

Passive Power Factor Correction (PFC) Calculator

Last Updated on April 15, 2026 by Swagatam Leave a Comment

This passive PFC calculator does not use any MOSFET or PWM or switching frequency. It only uses 50 Hz mains and it only works with inductors and capacitors, so the only thing that matters is the reactance of the inductor and the reactance of the capacitor at the mains frequency. That is why the calculator […]
