Viper22a Smps Circuit Diagram. The viper22a e combines a dedicated current mode pwm controller with a high voltage power mosfet on the same silicon chip. Typical applications cover off line power supplies for battery charger adapters standby power supplies for tv or monitors auxiliary supplies for motor control etc.

In the above image the maximum power 15w is shown. My board once the soldering job was done looked like this below testing viper22a circuit for 12v 1a smps. The circuit is built around a low power offline switcher tny266 ic1 photo transistor photo coupler el817 ic2 a flyback transformer x1 and some other easily available components.
In such a segment tny268pn could provide 15w output.
In this tutorial we will learn how to build a 12v smps circuit that would convert ac mains power to 12v dc with a maximum current rating of 1 25a. Current and voltage conventions table 10. The circuit diagram is very easy to understand let s study it with the following points. I ll go and take pics later the smps is in the lab and i m at home but there s not a lot to take pics of.
