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 Regulator for Bias with an input range from 7 V to 18 V and supporting up to 15 A load currents. The device can operate from a V Range: 4.5 V to 5.5 V with V /P /P IN IN VIN VCC Connected to Bypass Internal Regulator 5 V rail (10%) if V , P , and P are connected IN VIN VCC together to bypass the internal linear regulator. High Efficiency: Over 96% Peak The FAN23SV15MA utilizes Fairchilds constant on-time Continuous Output Current: 15 A control architecture to provide excellent transient Internal Linear Bias Regulator response and to maintain a relatively constant switching frequency. The device utilizes Pulse Frequency Accurate Enable facilitates VIN UVLO Functionality Modulation (PFM) mode to maximize light-load PFM Mode for Light-Load Efficiency efficiency by reducing switching frequency when the inductor is operating in discontinuous conduction mode Excellent Line and Load Transient Response at light loads. Precision Reference: 1% Over Temperature Switching frequency and over-current protection can Output Voltage Range: 0.6 to 5.5 V be programmed to provide a flexible solution for various applications. Output over-voltage, under- Programmable Frequency: 200 kHz to 1 MHz voltage, over-current, and thermal shutdown protections Programmable Soft-Start help prevent damage to the device during fault conditions. After thermal shutdown is activated, a Low Shutdown Current hysteresis feature restarts the device when normal Adjustable Sourcing Current Limit operating temperature is reached.
