ACT2802/ACT2802B integrates all the functions that a backup battery pack needs, including switching charger, boost converter and LED indication.
ACT2802/ACT2802B operates at 1.
1MHz for switching charger and 0.
55MHz for boost converter allowing tiny external inductor and capacitors.
ACT2802/ACT2802B provides a direct power path from input to output with programmable current limit while providing power to switching charger.
Output has higher priority than battery charger if the programmed input current limit is reached.
ACT2802/ACT2802B charges battery with full cycle of precondit...
