DescriptionThe FSQ0170RNA, FSQ0270RNA, FSQ0370RNA 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-frequency generating oscillator, Under-Voltage Lockout (UVLO) protection, Leading Edge Blanking (LEB), an optimized gate turn-on/ turn-off driver, Thermal Shutdown (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 FSQ0170RNA, FSQ0270RNA, FSQ0370RNA reduces total component count, design size, and weight while increasing efficiency, productivity, and system reliability. FSQ0370RNA provide a basic platform that is well suited for the design of cost-effective flyback converters, as in PC auxiliary power supplies.
