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.

To avoid acoustic- Adaptively Decrease PWM Frequency with noise problems, the minimum PWM frequency is set Cycle Skipping to 23 kHz at Light-Load above 23 kHz. This green-mode function enables the Condition for Better Efficiency power supply to meet international power conservation Feedback Impedance Switching During requirements, such as Energy Star . With the internal Minimum Load or No Load high-voltage startup circuitry, the power loss caused by bleeding resistors is also eliminated. To further reduce Proprietary Asynchronous Frequency Hopping power consumption, FAN6605 uses the BiCMOS Technique that Reduces EMI process, which allows an operating current of only Fixed PWM Frequency: 65 kHz 2 mA. The standby power consumption can be under 100 mW for most of LCD monitor power supply designs. Internal Leading-Edge Blanking FAN6605 integrates a frequency-hopping function that Built-in Synchronized Slope Compensation reduces EMI emission of a power supply with minimum Auto-Restart Protection: Feedback Open-Loop line filters. The built-in synchronized slope Protection (OLP), V Over-Voltage Protection DD compensation achieves a stable peak-current-mode (OVP), Over-Temperature Protection (OTP), and control and improves noise immunity. The proprietary Line Over-Voltage Protection line compensation ensures constant output power limit over a wide AC input voltage range from 90 V to AC Soft Gate Drive with Clamped Output Voltage: 18 V 264 V . AC V Under-Voltage Lockout (UVLO) DD FAN6605 provides many protection functions. The Programmable Constant Power Limit internal feedback open-loop protection circuit protects (Full AC Input Range) the power supply from open-feedback-loop condition or output-short condition. It also has line under-voltage Internal OTP Sensor with Hysteresis protection (brownout protection) and over-voltage Build-in 5-ms Soft-Start Function protection using an input voltage sensing pin (V ). IN Input Voltage Sensing (V Pin) for Brown-In/Out IN FAN6605 is available in a 7-pin SOP package.
