PMP30826 Reference Design

Texas Instruments

Offline supercapacitor backup power supply with active cell balancing reference design

Description

This reference design provides a backup voltage during a power interruption. It manages the charging of supercapacitors directly from the mains voltage (96 VAC - 272 VAC). The UCC28740 provides constant-voltage (CV) and constant-current (CC) output regulation. The supercapacitor capacitance and voltage define the energy that is available for the backup.
