Offline supercapacitor backup power supply with active cell balancing reference design

Details

TopologieSperrwandler
Eingangsspannung96-552 V
Ausgang 14 V / 3 A
IC-RevisionB

Beschreibung

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.

Eigenschaften

  • Electric double-layer capacitor charger
  • Protection functions: over voltage, low line, over current and short circuit
  • Active cell balancing
  • Complete tested design with available design files and test report

Typische Anwendungen

  • Single-phase electricity meter
