Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductors system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore ( ), the underscore ( ) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore ( ). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

It is specifically designed for high- performance off-line Switch-Mode Power Supplies Precision Fixed Operating Frequency: 100kHz (SMPS) with minimal external components. Internal Start-up Circuit and Built-in Soft-Start Pulse-by-Pulse Current Limiting and Auto-Restart The integrated PWM controller features include: a fixed- Mode frequency generating oscillator, Under-Voltage Lockout Over-Voltage Protection (OVP), Overload Protection (UVLO) protection, Leading-Edge Blanking (LEB), an (OLP), Internal Thermal Shutdown Function (TSD) optimized gate turn-on/turn-off driver, Thermal Under-Voltage Lockout (UVLO) Shutdown (TSD) protection, and temperature- Low Operating Current: 3mA compensated precision current sources for loop Adjustable Peak Current Limit compensation and fault protection circuitry. Compared to a discrete MOSFET and controller or RCC switching converter solution, the FSQ110 reduces total Applications component count, design size, and weight while increasing efficiency, productivity, and system reliability. SMPS for STB, Low-cost DVD These devices provide a basic platform that is well suited for the design of cost-effective flyback converters.
