Preliminary Datasheet LP28501 3.5A Synchronous Buck Li-ion Charger With Intelligent Path Management and Adapter Adaptive General Description The LP28501 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. The LP28501 includes complete charge termination circuitry, automatic recharge and a ±1% 4.2V/4.3V /4.35V float voltage. The LP28501 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. If the current capacity of adapter could not meet the system demand, the adapter and battery would supply power for system together.
