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.
