Datasheet:
The FSQ0370 consists of an integrated Current Mode Pulse Width Modulator (PWM) and an avalanche rugged 700V SenseFET. It is specifically designed for high-performance offline Switched 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 FSQ0370 reduces total component count, design size, and weight while increasing efficiency, productivity, and system reliability. These devices provide a basic platform that is well suited for the design of cost-effective flyback converters, such as in PC auxiliary power supplies.
