UCC28060EVM 300-W Interleaved PFC Pre-Regulator

The UCC28060 is a dual-phase, transition-mode Power Factor Correction (PFC) pre-regulator. The

UCC28060EVM is an evaluation module (EVM) with a 390-V, 300-W, dc output that operates from a

universal input of 85 V

RMS

to 265 V

RMS

and provides power-factor correction.

Throughout this document, the acronym EVM and the phrases evaluation board and evaluation module

are synonymous with the UCC28060EVM.

The pre-regulator uses the UCC28060 PFC interleaved controller to shape the input current wave to

provide power-factor correction. This device uses TI’s Natural Interleaving™ technology to interleave

boost phases.

This user’s guide provides the schematic, List of Materials list, assembly drawing for a single-sided printed

circuit board application, and test set-up information necessary to evaluate the UCC28060 in a typical

PFC application.

This evaluation module will operate up to 300 W without external cooling in ambient tempatures of 25 ° C.

Table 1 summarizes the electrical specifications of the UCC28060EVM.
