2A Synchronous Buck Li-ion Charger

General Description

The LP28300 is a 2A Li-Ion battery charger intended for5V

wall adapters. It utilizes a 1.5MHz synchronous buck

converter topology to reduce power dissipation during

charging. Low power dissipation, an internal MOSFET

allow a physically small charger that can be embedded in a

wide range of handheld applications. The LP28300 includes

complete charge termination circuitry, automatic recharge

and a ±1% 4.2V float voltage. Input short-circuit protection

is included so no blocking diode is required.

Battery charge current, charge timeout and end-of-charge

indication parameters are set with external components.

Additional

features

include

shorted

cell

detection,

temperature qualified charging and overvoltage protection.

The LP28300 is available in a low profile (0.75mm)

10-lead(3mm × 3mm)

DFN package.
