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.

The FSQ510 is an integrated Low EMI through Variable Frequency Control and Valley Switching Pulse Width Modulation (VS-PWM) Inherent Frequency Modulation controller and SenseFET specifically designed for High Efficiency through Minimum Drain Voltage offline Switch-Mode Power Supplies (SMPS) for valley Switching switching with minimal external components. The VS- PWM controller includes an integrated oscillator, under- Extended Valley Switching for Wide Load Ranges voltage lockout (UVLO), leading-edge blanking (LEB), Small Frequency Variation for Wide Load Ranges optimized gate driver, internal soft-start, temperature- compensated precise current sources for loop Advanced Burst-Mode Operation for Low Standby compensation, and self-protection circuitry. Power Consumption Compared with discrete MOSFET and PWM controller Pulse-by-Pulse Current Limit solutions, the FSQ510 can reduce total cost, Protection Functions: Overload Protection (OLP), component count, size and weight while simultaneously Internal Thermal Shutdown (TSD) with Hysteresis increasing efficiency, productivity, and system reliability. This device provides a platform for cost-effective designs Under-Voltage Lockout (UVLO) with Hysteresis of a valley switching flyback converters.
