Murata Power Solutions and pSemi (formerly Peregrine Semiconductor) have joined together to save development time of engineering power supplies by offering the PE22100 push-pull driver matched with the 782100 series transformer for isolated power supply applications. The PE22100 drives the primary of the 782100 center-tapped transformers from a 3.0 V or a 5 V supply to deliver an efficient, reliable isolated power supply.
