FSQ0370RNA / FSQ0370RLA — Green Mode Fairchild Power Switch (FPS™) March 2012 FSQ0370RNA, FSQ0370RLA Green Mode Fairchild Power Switch (FPS™) Features Description The FSQ0370 consists of an integrated Current Mode Internal Avalanche Rugged 700V SenseFET Pulse Width Modulator (PWM) and an avalanche rugged Consumes Only 0.8W at 230V & 0.5W Load with AC 700V SenseFET. It is specifically designed for high- Burst-Mode Operation performance offline Switched Mode Power Supplies (SMPS) with minimal external components. The Precision Fixed Operating Frequency: 100kHz integrated PWM controller features include: a fixed- Internal Startup Circuit and Built-in Soft-Start frequency generating oscillator, Under-Voltage Lockout (UVLO) protection, Leading-Edge Blanking (LEB), an Pulse-by-Pulse Current Limiting, Auto-Restart Mode optimized gate turn-on / turn-off driver, Thermal Over-Voltage Protection (OVP), Overload Shutdown (TSD) protection, and temperature- Protection (OLP), Internal Thermal Shutdown compensated precision current sources for loop Function (TSD) compensation and fault protection circuitry. Under-Voltage Lockout (UVLO) Compared to a discrete MOSFET and controller or RCC switching converter solution, the FSQ0370 reduces total Low Operating Current: 3mA component count, design size, and weight while Adjustable Peak Current Limit increasing efficiency, productivity, and system reliability. These devices provide a basic platform that is well suited for the design of cost-effective flyback converters, Applications such as in PC auxiliary power supplies.
