12v 1 amp smps circuit

In the following content I have explained two simple 12V, 1 Amp switch mode power supply (SMPS) circuit using the very reliable VIPerXX IC from ST microelectronics. With the advent of modern ICs and circuits, the age old iron transformer type of power supply are surely becoming obsolete. Today power supplies are much compact, smaller […]

Last Updated on January 8, 2024 by Swagatam 58 Comments

10WSMPSCircuitUsingSTMicroelectronicsVIPer22

SMPS is the acronym of the word Switch Mode Power Supply. The name clearly suggests that the concept has something or entirely to do with pulses or switching of the employed devices. I have explained how SMPS adapters work for converting mains voltage to a lower DC voltage. Advantage of SMPS Topology In SMPS adapters […]

INA219 Current Sensor Circuit Diagram and Datasheet

Last Updated on May 16, 2025 by Swagatam Leave a Comment

In this post we are going to understand this sensor called INA219, and this one is like a full smart sensor. It not only tells how much current is flowing but also tells voltage, and also calculates power, all in digital form. That means it talks with microcontroller through I2C lines. It is like an […]
