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.

It Quasi-Resonant Switching Operation with incorporates Quasi-Resonant (QR) control with Programmable Maximum Blanking Frequency proprietary Valley Switching with a limited frequency Range (60 kHz~ 140 kHz) variation. QR switching provides high efficiency by reducing switching losses while Valley Switching with a User Configurable Burst Mode Entry and Exit to limited frequency variation bounds the frequency band Maximize Light Load Efficiency and Minimize to overcome the inherent limitation of QR switching. Audible Noise FAN602 features mWSaver burst mode operation with Adaptive Burst Mode Entry Level for Adaptive extremely low operating current (300 A) and Charger Application significantly reduces standby power consumption to mWSaver Technology for Ultra Low Standby meet the most stringent efficiency regulations such as Power Consumption (<20 mW) Energy Stars 5-Star Level and CoC Tier II specifications. Forced and Inherent Frequency Modulation of Valley Switching for Low EMI Emissions and FAN602 includes several user configurable features Common Mode Noise aimed at optimizing efficiency, EMI and protections. FAN602 has a programmable blanking frequency range Built-In and User Configurable Over-Voltage that provides flexibility in choosing noise rejection in Protection (OVP), Under-Voltage Protection (UVP) targeted frequency zones. It incorporates user- and Over-Temperature Protection (OTP) configurable minimum peak current, which allows Fully Programmable Brown-In and Brownout controlling the burst mode entry/exit power level, Protection thereby enhancing light-load efficiency and eliminating audible noise. It also includes several rich Precise Constant Output Current Regulation with programmable protection features such as over-voltage Programmable Line Compensation protection (OVP), precise constant output current Built-In High-Voltage Startup to Reduce External regulation (CC).
