Page 1
... The IRF6645 is optimized for primary side bridge topologies in isolated DC-DC applications, for wide range universal input Telecom applications (36V - 75V), and for secondary side synchronous rectification in regulated DC-DC topologies. The reduced total losses in the device coupled with the high level of thermal performance enables high efficiency and low temperatures, which are key for system reliability improvements, and makes this device ideal for high performance isolated DC-DC converters ...
