I wrote about how N-channel MOSFET on the high side in buck converter design and why it will not work in my previous note Why High-Side N-Channel Buck Converters Fail . Although there is advantage to using n-channel on the side which is that the …
I posted about an open loop, non-synchronous, high side N-MOSFET diy Arduino based buck converter design earlier. But after researching, I came to know that it will not work. I need to rewrite that blog post. But before doing that I wanted to writ…
In my earlier Ubiquiti radio antenna repair note repairing Ubiquiti Lite AP 120 I said that I checked the various components on the PCB board. I checked the voltage regulator IC, the capacitors and inductors for any short circuit. I also posted U…
I wrote a about a simple shunt voltage regulator design with TL431 but circuit is usually not recommended for moderate to high current application or battery powered circuits. In the shunt mode, the TL431 will draw current from the source even if t…
There are many components that can be reused from old desktop PSU(Power Supply Unit). I have written about many components that can be salvaged from SMPS(Switch Mode Power Supply) like PC817 optocoupler that can be used to build Arduino inverter …
Using an external pass transistor with a voltage regulator like the 78XX series allows you to safely boost its current output beyond its internal limit. Using an external pass transistor with a 78XX regulator reduces the heating of the regulator i…
I have come across an IC that is used in diy Arduino Inverter and this IC is called MC34063 and I wanted to know what this IC is and where it is typically used. So this is note on this IC. The MC34063 is a DC-DC converter IC that can be configure…
I think its been 10 days now that I started to learn more about negative feedback amplifier and how to use it. I covered the 3 types of negative feedback amplifier, voltage amplifier , transimpedance amplifier , transconductance amplifier and cur…
