FSDH0370RNB General Description
The FSDH0170RNB/FSDH0270RNB/FSDH0370RNB consists of an integrated current mode Pulse Width Modulator (PWM) and an avalanche rugged 700V Sense FET. It is specifically designed for high performance offline Switch Mode Power Supplies (SMPS) with minimal external components. 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 current sources for loop compensation and fault protection circuitry. Compared to a discrete MOSFET and controller or RCC switching converter solution, the FSDH0170RNB/FSDH0270RNB/FSDH0370RNB reduces total component count, design size, and weight while increasing effi-ciency, productivity, and system reliability. These devices provide a basic platform that is well suited for the design of cost-effective flyback converters, as in PC auxiliary power supplies.
