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).
