Beschreibung
This design is auxiliary power supply with 5-V/1-A and 5-V/1-A dual output. The line and load regulation of the power supply is designed to be within 1% using the secondary side regulator, UCC28742. The system's reliability is improved through input UVLO and output OVP, OCP, SCP. The four point's load (25%, 50%,75%, 100%) average efficiency is above 81%.
Eigenschaften
- DCM valley-switching operation enable high efficiency at light load and better EMI performance
- Up to 1% line and load regulation enable output voltage high accuracy requirement
- Average efficiency above 81% simplifies the thermal design
Typische Anwendungen
- Appliances: battery charger / Substation automation
