Description
The FSDM0265RNB consists 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. This
devices is an integrated high voltage power switching regu-
lator which combines an avalanche rugged Sense FET with a
current mode PWM control block. The integrated PWM con-
troller features include: a fixed oscillator with frequency
modulation for reduced EMI, Under Voltage Lock Out
(UVLO) protection, Leading Edge Blanking (LEB), an opti-
mized gate turn-on/turn-off driver, Thermal Shut Down
(TSD) protection and temperature compensated precision
current sources for loop compensation and fault protection
circuitry. The FSDM0265RNB offers better performance in
Soft Start than FSDM0265RN. When compared to a discrete
MOSFET and controller or RCC switching converter solu-
tion, the FSDM0265RNB reduces total component count,
design size, weight while increasing efficiency, productivity
and system reliability. This device provides a basic platform
that is well suited for the design of cost-effective flyback
converters.
