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
Throughout this document, the acronym EVM and the phrases evaluation board and evaluation module
are synonymous with the UCC28060EVM.

Description
The pre-regulator uses the
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.
