There is a continuous need for higher power capability in most applications today. In some applications, a single MOSFET is not enough. In these applications, designers must share the current load among multiple MOSFETs in parallel.
Connecting MOSFETs in parallel while ensuring a rugged design which includes safe operation and reliability is a challenge. Current sharing among devices in parallel is often not well understood and can cause unexpected system failures in the field if not done properly.
Infineon has developed collaterals to explain these challenges and offer solutions to help designers apply the correct methodology in designing power converters. A demoboard showcasing MOSFETs in parallel is available: Low voltage drives scalable power demonstration board
