SELECTION OF COMPONENTS
Pch MOS FET
The P-ch MOSFET for switching use should be rated for at least 20% more than the maximum input voltage. To
minimize continuity loss, use a FET with low R
DS(ON)
between the drain and source. For high input voltage and
high frequency operation, on/off-cycle switching loss will be higher so that power dissipation must be considered.
In this application, the Toshiba TPC8102 is used. Continuity loss, on/off switching loss, and total loss are deter-
mined by the following formulas. The selection must ensure that peak drain current does not exceed rated values,
and also must be in accordance with overcurrent detection levels.
