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 Random Frequency Fluctuation for Low EMI oscillator, Under-Voltage Lockout (UVLO), Leading- Pulse-by-Pulse Current Limit Edge Blanking (LEB), optimized gate driver, internal soft-start, temperature-compensated precise current Various Protection Functions: Overload Protection sources for loop compensation, and self-protection (OLP), Over-Voltage Protection (OVP), Abnormal circuitry. Compared with a discrete MOSFET and PWM Over-Current Protection (AOCP), Internal Thermal controller solution, the FSL136MRT can reduce total Shutdown (TSD) with Hysteresis, and Under-Voltage cost, component count, size, and weight while Lockout (UVLO) with Hysteresis simultaneously increasing efficiency, productivity, and system reliability. This device provides a basic platform Low Operating Current (0.4mA) in Burst Mode suited for cost-effective design of a flyback converter.
