47 µH Inductor, 0603 Case Size Input / Output Capacitors  Total Application Board Solution Size: < 11 mm2 Applications  Class-D Audio Amplifier and USB OTG Supply  Boost for Low-Voltage Li-Ion Batteries  Smart Phones, Tablets, Portable Devices Description 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.
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.
