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 oscillator, Under- Pulse-by-Pulse Current Limit Voltage Lockout (UVLO), Leading-Edge Blanking (LEB), Various Protection Functions: Overload Protection optimized gate driver, internal soft-start, temperature- (OLP), Over-Voltage Protection (OVP), Abnormal compensated precise current sources for loop Over-Current Protection (AOCP), Internal Thermal compensation, and self-protection circuitry. Compared Shutdown (TSD) with Hysteresis, Output-Short with a discrete MOSFET and PWM controller solution, Protection (OSP), and Under-Voltage Lockout the FSD146MRBN can reduce total cost, component (UVLO) with Hysteresis count, size, and weight while simultaneously increasing efficiency, productivity, and system reliability. This Low Operating Current (0.4mA) in Burst Mode device provides a basic platform that is well suited for Internal Startup Circuit cost-effective design of a flyback converter.
