Supercapacitor backup power supply with current limit and active cell balancing reference design

This reference design automatically provides a back-up voltage during a power interruption. It manages the charging of supercapitors and provides reverse blocking protection. The maximum supercapacitor charging current and voltage can be adjusted. When the input voltage fails a buck-boost converter (...)
