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
STTA12006TV1/2 / STTA6006P
transistor, thus optimizing the overall performance
in the end application.
The way of calculating the power losses is given
below:
TOTAL LOSSES
