... Demonstration board description 1 Demonstration board description The STEVAL-ISA018V1 board is based on an LLC resonant converter, and employs the 5 Ω, 500 V STF21NM50N power MOSFET as the primary switches in the half-bridge. The STF21NM50N is produced using STMicroelectronics’ proprietary high voltage MDmesh™ II technology. Thanks to this technology, the switch features a very low R gate charge and high switching performance ...
