LP28601 - 3.5A Synchronous Buck Li-ion Charger

Description

The LP28601 is a 3.5A Li-Ion battery charger intended for 4.4V~14V wall adapters.

It utilizes a high efficiency synchronous buck converter topology to reduce power dissipation during charging.

And a synchronous step up function could supply 5V/2A from Li-Ion battery which can be used as the OTG.

Features

  • include shorted cell detection; temperature qualified charging and overvoltage protection. The LP28601 is available in a low profile QFN-28 package. Order Information LP28601.
  • F: Pb-Free Package Type QV: QFN-28.

Preliminary Datasheet LP28601 3.5A Synchronous Buck Li-ion Charger With Intelligent Path Management，Adapter Adaptive and OTG General Description The LP28601 is a 3.5A Li-Ion battery charger intended for 4.4V~14V wall adapters. It utilizes a high efficiency synchronous buck converter topology to reduce power dissipation during charging. And a synchronous step up function could supply 5V/2A from Li-Ion battery which can be used as the OTG. The LP28601 includes complete charge termination circuitry, automatic recharge and a ±1% 4.2V/4.3V /4.35V float voltage. The LP28601 could manage the power supply for system intelligently. The adapter would satisfy the system`s demand firstly, then charge battery with extra current output capacity from adapter.
