ESOP-8/DFN-10
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. 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/TDFN-10 3*3mm and package.
Applications
2 cell Li-Ion handheld devices
POS device
Bluetooth speaker
USB powered devices
Features
Input voltage range 4.5V~18V
Dynamic input current allocation for maximum charging rate
