The LP28303A is a 2.5A Li-Ion battery charger. It utilizes a 600KHz synchronous buck converter topology to reduce power dissipation during charging. Low power dissipation and internal MOSFET allow a physically small charger that can be embedded in a wide range of handheld applications. The LP28303Aincludes complete charge termination circuitry,automatic recharge and ±1% 4.2V float voltage.
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 LP28303A is available in a low profile ESOP8&DFN-10（3*3mm） package.
