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 PWM controller includes an integrated fixed-frequency Pulse-by-Pulse Current Limit oscillator, Under-Voltage Lockout (UVLO), Leading- Various Protection Functions: Overload Protection Edge Blanking (LEB), optimized gate driver, internal (OLP), Over-Voltage Protection (OVP), Abnormal soft-start, temperature-compensated precise current Over-Current Protection (AOCP), Internal Thermal sources for loop compensation, and self-protection Shutdown (TSD) with Hysteresis, Output-Short circuitry. Compared with a discrete MOSFET and PWM Protection (OSP), and Under-Voltage Lockout (UVLO) controller solution, the FSL176MRT can reduce total with Hysteresis cost, component count, size, and weight while simultaneously increasing efficiency, productivity, and Low Operating Current (0.4mA) in Burst Mode system reliability. This device provides a basic platform Internal Startup Circuit for cost-effective design of a flyback converter.
