Description
The FAN4860 is a low-power boost regulator designed to
provide a regulated 5V output from a single cell Li-Ion
battery. The output voltage is fixed at 5.0V with a guaranteed
maximum load current of 200mA at VIN=2.3V and 300mA at
VIN=3.3V. Input current in shut-down mode is less than 1µA,
which maximizes battery life.
Light-load PFM operation is automatic and “glitch-free”. The
regulator maintains output regulation at no-load with 37µA
quiescent current.
The combination of built-in power transistors, synchronous
rectification, and low supply current make the FAN4860 ideal
for battery powered applications.
The FAN4860 is available in 6-bump 0.4mm pitch Wafer-
Level Chip Scale Package (WLCSP) and a 6-lead 2x2mm
ultra-thin MLP package.
