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.
