STTA1206D/DI/G
APPLICATION DATA
The TURBOSWITCH is especially designed to
provide the lowest overall power losses in any
“FREEWHEEL
Mode”
application
(Fig.A)
considering both the diode and the companion
transistor, thus optimizing the overall performance
in the end application.
The way of calculating the power losses is given
below:
