Green Mode Power Switch
FSDM0265RNB,
FSDM0365RNB
Description
The FSDM0x65RNB of integrated Pulse Width Modulator (PWM)
and SENSEFET® are specifically designed for high performance
offline Switch Mode Power Supplies (SMPS) with minimal external
components. This devices is an integrated high voltage power
switching regulator which combines an avalanche rugged SENSEFET
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
turnon/turnoff driver, Thermal Shut Down (TSD) protection and
temperature compensated precision current sources for loop
compensation and fault protection circuitry. The FSDM0x65RNB
offers better performance in Soft Start than FSDM0265RN. When
compared to a discrete MOSFET and controller or RCC switching
converter solution, the FSDM0x65RNB 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 costeffective flyback converters.
