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.

Output voltage options are fixed Input Voltage Range from 2.3 V to 5.4 V at 3.3 V, 5.0 V, or 5.4 V with a guaranteed maximum load Fixed 3.3 V, 5.0 V, or 5.4 V Output Voltage Options current of 200 mA at V =2.3 V and 300 mA at V =3.3 V. IN IN Input current in Shutdown Mode is less than 1 A, which Maximum Load Current >150 mA at V =2.3 V IN maximizes battery life. Maximum Load Current 300 mA at V =3.3 V, V =5.4 V IN OUT Light-load PFM operation is automatic and glitch-free. The Maximum Load Current 300 mA at V =3.3 V, V =5.0 V IN OUT regulator maintains output regulation at no-load with as low as 37 A quiescent current. Maximum Load Current 300 mA at V =2.7 V, V =3.3 V IN OUT The combination of built-in power transistors, synchronous Up to 92% Efficient rectification, and low supply current make the FAN4860 ideal Low Operating Quiescent Current for battery powered applications. True Load Disconnect During Shutdown The FAN4860 is available in 6-bump 0.4 mm pitch Wafer- Level Chip Scale Package (WLCSP) and a 6-lead 2x2 mm Variable On-time Pulse Frequency Modulation (PFM) with ultra-thin MLP package.
