Push-Pull Transformer Drivers?

This article explains how to quickly set up push-pull driver circuits for pulse transformers in low-power isolated dc-dc power supplies.

I also speak about some of the ubiquitous push-pull converter chips that are specifically designed to drive such low-profile centre-tapped transformers... ⇲

⫸ Electrons and Holes in Semiconductors with Applications to Transistor Electronics is a book by Nobel Prize winner William Shockley, first published in 1950...

It was a primary source, and was used as the first textbook, for scientists and engineers learning the new field of semiconductors as applied to the development of the transistor...

This was the invention that led to electronic computers, ubiquitous communication devices, compact electronics controllers, and a host of other important inventions of the last half of the twentieth century...

The book was printed by D. Van Nostrand in New York, and went through many later printings...
