Supercapacitor Backup Power Supply with Active Cell Balancing Reference Design
Texas Instruments
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.
Features
- No glitches at the automatic transition from main power to backup power operationActive cell balancingBackup-capacitor type and size are selectable to meet backup power needsUp to 15 Watt output powerSmall and high efficiency single converter solutionSupport of pulsed loads connected to a weak supply
