FAN48615 Fixed-Output Synchronous TinyBoost Regulator Description The FAN48615 is a low power PWM only boost regulator designed to provide a minimum voltageregulated rail from a standard www.onsemi.com singlecell LiIon battery and advanced battery chemistries. Even below the minimum system battery voltage, the device maintains the output voltage regulation for an output load current of 1000 mA. The combination of builtin power transistors, synchronous rectification, and low supply current suit the FAN48615 for batterypowered WLCSP9 applications. CASE 567QW The FAN48615 is available in a 9bump, 0.4 mm pitch, (1.215 x 1.215 mm) WaferLevel ChipScale Package (WLCSP).
