Description
This reference design uses a UCC28064A, Natural Interleaving(TM) transition-mode power factor correction (PFC) controller to provide a universal AC input to 380-V/700-W conversion. This design achieves 98% peak efficiency at the 230 VAC input and the light-load efficiency is maintained at a level close to full-load efficiency because of the burst mode operation provided by UCC28064A. This is an advantageous feature for customers who want to meet certain standards (i.e.: 80PLUS) with light-load efficiency requirements.
Features
- Interleaving transition-mode PFC with improved light load efficiency
- Universal AC input, 385-V/700-W output
- Over 94.5% efficiency from 5% load to 100% load at 115VAC input
- Over 96% efficiency from 5% load to 100% load at 230VAC input
- Achieve 98% peak efficiency at 230VAC input
