In this post I will explain a very basic 12V to 220V AC inverter design using IC 555 as the oscillator stage, for generating a 50Hz frequency to the MOSFET driver stage of the inverter. We have used a center tap transformer for this design which effectively converter the battery 12V into 220V AC 50 […]

220V AC to 12V DC Flyback SMPS Circuit using IC 555 (7555)
This practical flyback SMPS circuit uses ICM7555 as the main oscillator, and yep the whole idea is to take 220V AC mains directly then convert it into isolated low voltage DC through a ferrite transformer.. Unlike many PWM controller designs, here we have very few parts but still it gives mains isolation, voltage feedback, current […]
XL6009 DC-DC Converter IC: Pinout, Working, Circuit Diagram, and Applications
XL6009 is a DC-DC switching regulator IC, and we use it where lower voltage DC has to be lifted higher, or sometimes changed other ways, boost, buck-boost, flyback, even inverting, all that is possible depending how outside parts are connected. Why XL6009 is More Efficient Than Linear Regulators It is not like old regulator types […]
220V AC to 56V DC SMPS Circuit for 48V Battery Charging
In this article we will try to understand how to build a 220V AC to 48 V DC SMPS circuit for charging all types of 48V batteries, using the nice little IC IR2153. However, since 48V battery will require a 56V DC, so we will rather discuss a 220V to 56 V DC battery charger […]
Adjustable 1.2V to100V DC Buck Converter Circuit using LM5164
Ok now we have this LM5164 chip, and we want to drop voltage from 100V down to let’s say 12V, right? But we also need 1A output so we need to design everything properly. Now this chip is cool because it has ultra-low quiescent current (IQ) so it does not waste much power when it […]
DC-DC Boost Module (0.9V~5V) to 5V 600mA USB Step-up Board
So this is a DC-DC boost converter that takes a low voltage (0.9V to 5V) and steps it up to a stable 5V. We use this when we have a small battery, but we need 5V output, like for USB devices. It is super useful for battery-powered projects and small electronics. Main Features How It […]
