Beschreibung
- PMP8920, High efficiency two-stage universal input power supply using transition mode PFC and LLC resonant converter. Low EMI, high efficiency, high power factor and reliable power supply are main focus of the PMP8920 design for telecom applications. Transient mode power factor correction (PFC) with UCC28051 and LLC series resonant converter (SRC) with UCC25600 are applied in PMP8911. In addition, synchronous rectifier (SR) IC UCC24610 is applied to LLC output rectifier stage. Low EMI is expected with zero voltage switching on TM-PFC and LLC-SRC switches. An overall 91% efficiency is achieved at 100W full load. In addition, several protections are embedded into this design which includes input under-voltage protection, input over-voltage protection, output over-voltage protection, and output hic-cup over-power protection
