LP28300 - 2A Synchronous Buck Li-ion Charger

General Description

The LP28300 is a 2A Li-Ion battery charger.

It utilizes a 500KHz 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.

Key Features

  • include shorted cell detection; temperature qualified charging and overvoltage protection. The LP28300 is available in a low profile ESOP8 and package. Order Information LP28300.
  • F: Pb-Free Package Type SP: ESOP8 QV: TDFN-10 Charge voltage A: 4.2V B: 8.4V C: 12.6V.

Preliminary Datasheet LP28300 2A Synchronous Buck Li-ion Charger General Description The LP28300 is a 2A Li-Ion battery charger. It utilizes a 500KHz 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 / 8.4V / 12.6V 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 LP28300 is available in a low profile ESOP8 and package.
