PMP9766, Supercapacitor Backup Power Supply with Active Cell Balancing Reference Design

PMP9766, Supercapacitor Backup Power Supply with Active Cell Balancing Reference Design. This reference design describes a backup power circuit which addresses instantaneous protection against power interruptions by using a buck-boost converter and two stacked supercapacitors. The implementation is based on a completely integrated TPS63020 buck-boost converter circuit enabling a small total solution size. The design also provides an active cell balancing circuit. This configuration has been tested with a full test report and operation explanation
