The FAN4860 is a low-power boost regulator designed to
provide a regulated 3.3 V, 5.0 V or 5.4 V output from a single
cell Lithium or Li-Ion battery. Output voltage options are fixed
at 3.3 V, 5.0 V, or 5.4 V with a guaranteed maximum load
current of 200 mA at V IN =2.3 V and 300 mA at V IN =3.3 V.
Input current in Shutdown Mode is less than 1 μA, which
maximizes battery life.
Light-load PFM operation is automatic and “glitch-free”. The
regulator maintains output regulation at no-load with as low
as 37 μA 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 0.4 mm pitch Wafer-
Level Chip Scale Package (WLCSP) and a 6-lead 2x2 mm
ultra-thin MLP package.
