Fixed-Output Synchronous Regulator, TINYBOOST , 2.5 MHz FAN48610 Description www.onsemi.com The FAN48610 is a low-power boost regulator designed to provide a minimum voltage-regulated rail from a standard single-cell Li-Ion battery and advanced battery chemistries. Even below the minimum system battery voltage, the device maintains the output voltage regulation for a minimum output load current of 1.0A. The combination of built-in power transistors, synchronous rectification, WLCSP9 and low supply current suit the FAN48610 for battery-powered CASE 567QW applications. The FAN48610 is available in a 9-bump, 0.4 mm pitch, Wafer-Level MARKING DIAGRAM Chip-Scale Package (WLCSP).
