4A Power Bank Solution APPLICATIONS • Power Bank • Mobile Power • Backup Battery Pack • Standalone Battery Charger with USB Output GENERAL DESCRIPTION ACT2813/ACT2813C is a space-saving and highperformance low-profile single-chip solution for backup battery pack and standalone battery charger.
ACT2813/ACT2813C integrates all the functions that a backup battery pack needs, including switching charger, boost converter and LED indication.
ACT2813/ACT2813C operates at 1.
1MHz for switching charger and 0.
55MHz for boost converter allowing tiny external inductor and capacitors.
ACT2813/ACT2813C provides a direct power path from input to output while providing power to switching charger.
Output has higher priority than battery charger if the input current limit is reached.
ACT2813/ACT2813C charges battery with full cycle of preconditioning, fast charge with constant current and constant voltage until end of charge.
The battery charger is thermally regulat...
