Battery backup unit (BBU)
Overview
Our integrated circuits and reference designs help you create high efficiency, high power density AC/DC and DC/DC battery backup units (BBUs) for various server power supply units (PSU), telecom PSU and industrial applications.
Design requirements
Modern BBUs often require:
- Fast charging to backup mode transition.
- High power density to pack more power in less space.
- High efficiency to extend battery backup time.
