Application Note 4116
A Fairchild Power Switch (FPS) based on
Switched Mode Power Supply for LCD Monitor Use
1. Introduction
This application note describes a complete flyback switched
mode power supply that uses a Fairchild Power Switch. The
MOSFET and its control IC are built into one package. The
MOSFET is in fact a SenseFET. Various protection features
are also included. Fairchild Power Switch can enhance the
reliability and productivity of the system when compared to
other designs. The FS6M series has a more avalanche rugged
SenseFET than the previous Fairchild Power Switch series.
The FS6M series features include burst mode operation for
low power consumption in DPMS mode. This application
note describes the features and design considerations of the
FS6M series for the LCD monitor power supply and adaptor,
which improves upon the existing KA5X-series.
FS6Mxx652RT has one package type: TO-220F-5L as
shown below. Fairchild Power Switch is classified according
to the voltage and current rating of the internal SenseFET.
The FS6M series parts with absolute voltage and absolute
current ratings of 650V/7A and 650V/12A. When in power
saving mode, the FS6M series pulls down the output
voltages to a predetermined level and enters burst mode with
a switching frequency of 70kHz.
