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.

This device integrates a <120 mW at 230 V without External Bias high-voltage power regulator that enables operation AC without auxiliary bias winding. An internal No Need for Auxiliary Bias Winding transconductance amplifier reduces external Frequency Modulation for Attenuating EMI components for the feedback compensation circuit. Pulse-by-Pulse Current Limiting The integrated PWM controller includes: 10 V regulator for no external bias circuit, Under-Voltage Lockout Ultra-Low Operating Current: 250 A (UVLO), Leading-Edge Blanking (LEB), an optimized Built-in Soft-Start and Startup Circuit gate turn-on / turn-off driver, EMI attenuator, Thermal Shutdown (TSD), temperature-compensated precision Adjustable Peak Current Limit current sources for loop compensation, and fault- Built-in Transconductance (Error) Amplifier protection circuitry. Protections include: Overload Protection (OLP), Over-Voltage Protection (OVP), and Various Protections: Overload Protection (OLP), Feedback Open Loop Protection (FB OLP). FSL336LR Over-Voltage Protection (OVP), Feedback offers good soft-start performance during startup. Open-Loop Protection (FB OLP), Thermal Shutdown (TSD) The internal high-voltage startup switch and the Burst- Mode operation with very low operating current reduce Fixed 650 ms Restart Time for Safe Auto-Restart the power loss in Standby Mode. As the result, it is of All Protections possible to reach power loss of 120 mW without external bias and 25 mW with external bias when input Applications voltage is 230 V .
