LP28300 Datasheet | POWER

Preliminary Datasheet 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 plete 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 ponents....
