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 regulator is capable of operating with an High Efficiency: Over 96% Peak input range from 4.5 V to 18 V and supporting up to 15 A load currents. Continuous Output Current: 15 A The FAN2315A utilizes Fairchilds constant on-time PFM Mode for Light-Load Efficiency control architecture to provide excellent transient Excellent Line and Load Transient Response response and to maintain a relatively constant switching frequency. The device utilizes Pulse Frequency Precision Reference: 1% Over-Temperature Modulation (PFM) mode to maximize light-load Output Voltage Range: 0.6 to 5.5 V efficiency by reducing switching frequency when the inductor is operating in discontinuous conduction mode Programmable Frequency: 200 kHz to 1 MHz at light loads. Programmable Soft-Start Switching frequency and over-current protection can Low Shutdown Current be programmed to provide a flexible solution for various applications. Output over-voltage, under- Adjustable Sourcing Current Limit voltage, over-current, and thermal shutdown protections Internal Boot Diode help prevent damage to the device during fault conditions. A hysteresis feature restarts the device Thermal Shutdown when normal operating temperature is reached.
