UCC28063EVM-723: 300W PFC, 390V, 85~265V in


The UCC28063 is a dual-phase, transition-mode Power Factor Correction (PFC) pre-regulator. The UCC28063EVM-723 is an evaluation module (EVM) with a 390-V, 300-W, dc output that operates from a universal input of 85 VRMS to 265 VRMS and provides power-factor correction.

The pre-regulator uses the UCC28063 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 evaluation module will operate up to 300 W without external cooling in ambient tempatures of 25°C.
