Protecting Flyback Converters During Short Circuit Testing

Riverside, California - October 30, 2015 - Bourns is pleased to announce the release of the Offl ine Flyback Converter Short Circuit Protection PortNote® Solution and Design Kit. Non-isolated low power offl ine fl yback converters are used in a variety of different applications such as AC adaptors, E-meters, and battery chargers. Such converters produce high peak currents which can damage the output diode during short circuit testing. 

This PortNote® Solution illustrates how a high temperature polymer PTC (Bourns® Model MF-RHT070-0) can help prevent the diode from being damaged during testing and how this can be a simple, low costsolution for engineers designing offl ine power supplies. 

The new PortNote® Solution and Design Kit are available on the Bourns website at www.bourns.com. For an online video demonstration, please visit Bourns Videos on YouTube.
