Inductor calculator

Choosing an inductor with the right amount of inductance requires you to consider many factors.

When using this calculator, you at least have a starting point from where to continue your design process.

Hacking a DC to DC converter
Introduction This is a follow-up of a proof of concept I made two months ago. I used an Arduino based DAC (8 bit 8 resistor) and an op-amp to create a signal...
How to add dead time to PWM
There are situations where you absolutely want to avoid signals overlapping one another. This is when you get introduced to the term dead-time. I will give you an example of a circuit...
Ten ways to drive a MOSFET, with examples
These are a couple of circuits that can drive a MOSFET. Each of them has their own pros and cons, so whether or not they are useful is highly dependent of what...
How to make an op-amp output PWM with duty-cycle control?
We can use a generic op-amp like the LM4562NA. We build an oscillator from the first op-amp in the IC. This produces a triangle-wave. We feed this wave into the second op-amp....
How does an op-amp work?
Op-amp is short for operational-amplifier. You can use it as a comparator, buffer a signal, or amplify a signal. These are some op-amps I have; they are the LM358 and the LM4562....
