LP28303A - 2.5A Synchronous Buck Li-ion Charger

General Description

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.

Key Features

  • include shorted cell detection; temperature qualified charging and overvoltage protection. The LP28303A is available in a low profile ESOP8&TDFN-10 and package. Order Information LP28303A F: Pb-Free Package Type SP: ESOP-8 QV: TDFN-10.
