The CS resistor should be as close as possible to the
CS pin, and makes the connection to the VCC bypass
capacitor as short as possible.
The Area of Power Loop
The area of main current loop should be as small as
possible to reduce EMI radiation, such as the
inductor, the power MOSFET, the output diode and
the bus capacitor loop.
CS Pin
To increase the copper area of CS pin for better
thermal dissipation.

KF16N25D

MOSFET의 기능은 N Channel MOS Field effect transistor입니다. This planar stripe MOSFET has better characteristics, such as fast switching time, low on resistance, low gate charge and excellent avalanche characteristics. It is mainly suitable for DC/DC Converters and switching mode power supplies.( Vdss=250V, Id=13A )
