LTC4080X
500mA Standalone Li-Ion
Charger with Integrated 300mA
Synchronous Buck in 3mm × 3mm DFN
DescripTion
The
LTC
®
4080X
is a complete constant-current/constant-
voltage linear battery charger for a single-cell 4.2V
lithium-ion/polymer battery with an integrated 300mA
synchronous buck converter. A 3mm
×
3mm DFN package
and low external component count make the LTC4080X
especially suitable for portable applications. Furthermore,
the LTC4080X is specifically designed to work within USB
power specifications.
The
CHRG
pin indicates when charge current has
dropped to ten percent of its programmed value (C/10).
An internal 4.5 hour timer terminates the charge cycle.
The full-featured LTC4080X battery charger also includes
automatic recharge and soft-start to limit inrush current.
If trickle charging is desired, please see the LTC4080
data sheet.
The LTC4080X integrates a synchronous buck converter
that is powered from the BAT pin. It has an adjustable output
voltage and can deliver up to 300mA of load current. The
buck converter also features low-current high-efficiency
Burst Mode operation that can be selected by the MODE pin.
The LTC4080X is available in 10-lead, low profile (0.75 mm)
3mm
×
3mm DFN and 10-lead MSE packages.
