Description

The FSDM0265RNB consists of an integrated Pulse Width Modulator (PWM) and Sense FET, and is 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 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 turnon/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 solution, the FSDM0265RNB reduces total component count, design size, weight while increasing efficiency, productivityand system reliability. This device provides a basic platform that is well suited for the design of cost-effective flyback converters.
