APPLICATION DATA
The TURBOSWITCHTM is especially designed to
provide the lowest overall power losses in any
“Freewhell Mode” application (see fig. A)
considering both diode and companion transistor,
thus optimizing the overall performance in the end
application.

The way of calculating the power losses is given
below :
TOTAL LOSSES
due to the diode
P = P1+ P2+ P3+ P4+ P5 Watts
