Beschreibung
This 12-V, 42-A output half-bridge reference design is for bus converters in wired networking campus and branch switches. The design features high efficiency and various fault protections (over-current, short-circuit). The guide provides a efficiency comparison using 3kVrms basic and functional isolated gate driver UCC21220D, UCC21220AD, UCC21222D and 5.7-kVrms reinforced isolated gate driver UCC21540D, UCC21540DWK and UCC21541DW.
Eigenschaften
- Peak efficiency up to 94.62%
- Lower system cost through integrating 100-V auxiliary bias converter
- Enhanced cycle-by-cycle current limit with pulse matching
- Fully regulated pre-biased start-up
Typische Anwendungen
- Industrial power supplies and factory automation / Test, measurement equipment
- Bus converters in wired networking campus and branch switches
