Smps Transformer Diagram. In such a segment tny268pn could provide 15w output. Smps circuit is operated by switching and hence the voltages vary continuously.
The isolation of voltage can be achieved by means of a transformer. It is enhanced energy efficient and low power offline switching device. This smps can be supplied with varying input voltages ie between ac voltages between 90 265v smps is still able to provide a stable output voltage.
Main three parts of this simple smps circuit are tny267 tiny switch ii family ic from power integrations.
However we will make the smps in the open frame and for the universal input rating. In the above image the maximum power 15w is shown. The switching frequency is around 100 khz. However we will make the smps in the open frame and for the universal input rating.
