Even below the minimum system battery voltage, the device maintains the output voltage regulation for a minimum output load current of 1.0 A. The combination of built-in power transistors, synchronous rectification, and low supply current suit the FAN48610 for battery-powered applications. The FAN48610 is available in a 9-bump, 0.4 mm pitch, Wafer-Level Chip-Scale Package (WLCSP). + Battery 0.47µH L1 VIN CIN 10µF SW FAN48610 VOUT COUT 22µF PGND SYSTEM LOAD EN AGND Figure...
