FAN48610
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, 0.4 mm pitch, Wafer-Level
Chip-Scale Package (WLCSP).
Features
Input Voltage Range: 2.5 V to 4.8 V
Output Voltages Range: 3.0 V to 5.0 V
IOUT 1 A at VOUT = 5.0 V, VIN 2.5 V
IOUT 1.5 A at VOUT = 5.0 V, VIN 3.0 V
