Description
Each product in the FSDx0365RNB (x for L, M) family con-
sists of an integrated Pulse Width Modulator (PWM) and
Sense FET, and is specifically designed for high performance
off-line Switch Mode Power Supplies (SMPS) with minimal
external components. Both devices are integrated high voltage
power switching regulators which combine an avalanche rug-
ged Sense FET with a current mode PWM control block. The
integrated PWM controller features include: a fixed oscillator
with frequency modulation for reduced EMI, Under Voltage
Lock Out (UVLO) protection, Leading Edge Blanking (LEB),
an optimized gate turn-on/turn-off driver, Thermal Shut Down
(TSD) protection and temperature compensated precision cur-
rent sources for loop compensation and fault protection cir-
cuitry. The FSDx0365RNB offers better performance in Soft
Start than FSDx0365RN. When compared to a discrete MOS-
FET and controller or RCC switching converter solution, the
FSDx0365RNB devices reduce total component count, design
size, weight while increasing efficiency, productivity, and sys-
tem reliability. Both devices provide a basic platform that is
well suited for the design of cost-effective flyback converters.

7. Frequency Modulation : Modulating the switching fre-
quency of a switched power supply can reduce EMI. Fre-
quency modulation can reduce EMI by spreading the energy
over a wider frequency range than the bandwidth measured
by the EMI test equipment. The amount of EMI reduction is
directly related to the depth of the reference frequency. As
can be seen in Figure 9, the frequency changes from 65KHz
to 69KHz in 4ms for the FSDM0365RNB (48.5KHz to
51.5KHz for FSDL0365RNB). Frequency modulation
allows the use of a cost effective inductor instead of an AC
input mode choke to satisfy the requirements of world wide
EMI limits.
