Preliminary
EUP8080
500mA Li-Ion Charger with Integrated
600mA Synchronous Buck Converter
DESCRIPTION
The EUP8080 is a complete constant-current/
constant-voltage linear battery charger for a single-cell
4.2V lithium-ion battery with an integrated 600mA
synchronous buck converter. It is specifically designed to
work within USB power specifications.
The battery charger offers an integrated pass device,
reverse blocking protection, high accuracy current and
voltage regulation, charge status, and charge termination.
The charging current is programmable via external resistor
from 15mA to 500mA. In addition to these standard
features, the device offers current limit, thermal protection,
and soft-start.
The EUP8080 integrates a synchronous buck converter
that is powered from the BAT pin internally. It has an
adjustable output voltage and can deliver up to 600mA of
load current. The buck converter also features low-current
high-efficiency Power Save and low output ripple PWM
mode operation that can be selected by the MODE pin.
The EUP8080 is available in a 10-lead, 3mm
