2. POWER MOSFET INTRODUCTION
The Power MOSFET is a type of MOSFET. The operating
principle of power MOSFET is similar to the general
MOSFET. The power MOSFETS are very special to handle
the high level of powers. It shows the high switching speed
and by comparing with the normal MOSFET, the power
MOSFET will work better. The power MOSFETs is widely
used in the n-channel enhancement mode, p-channel
enhancement mode, and in the nature of n-channel
depletion mode. The design of power MOSFET was made
by using the CMOS technology and also used for
development of manufacturing the integrated circuits in
the 1970s.

15. Applications of Power MOSFET
• The power MOSFET’s are used in the power
supplies
• DC to DC converters
• Low voltage motor controllers
• These are widely used in the low voltage
switches which are less than the 200V

16. Applications of P Channel Power MOSFET
• The main advantage of a P-channel device is
the reduction of design complexity in medium
and low power applications. P-channel power
MOSFETs are ideally suited for battery
protection, reverse polarity protection, linear
battery chargers, load switched, DC-DC
converters and low voltage drive applications.
P-channel MOSFETs are often used
in consumer electronics, such as notebook,
laptops, cellphones and PDAs.
