EVAL_40W_FLY_P7_950V

This 40W adapter reference board is intended to be a form, fit and function test platform for low cost charger applications to show the state-of-art 950V CoolMOS™ P7 superjunction (SJ) MOSFET (IPA95R450P7).  The  board is designed to fit a very small form factor while maintaining high efficiency, low standby power and various modes of protection for a highly reliable system. The 950V CoolMOS™ P7 has a higher breakdown voltage allowing use in applications which require a high input voltage or gives increased design flexibility to reduce losses in the snubber network.

The board shows how to use the 950V CoolMOS™ P7 in a snubberless flyback converter with up to 40W of output power.  By eliminating the snubber network the cost of the snubber can be removed while increasing efficiency and eliminating the PCB hotspot caused by the snubber network. This gives additional design flexibility to increase power density or reduce system costs.
