Apr 15, 2017 SLUS767E MAY 2007 REVISED NOVEMBER 2008. All voltages are with respect to GND, 40 C < TJ = TA < +125 C, and currents are positive into and negative out of the specified terminal, unless otherwise noted. UCC28060 . UNIT. VCC(2). 0.5 to +21. PWMCNTL. 0.5 to +20. Input voltage range. V. 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 VRMS to 265 VRMS and provides power-factor correction. Throughout this document, the acronym PR735 is an interleaved dual-phase transition-mode PFC converter providing a fixed 400-V output at up to. 1.5 A from an 85 VRMS to 265 VRMS ac input supply. This reference design requires an additional bias voltage of 15 V at 100 mA to power the UCC28060 device. PR735 is designed to showcase the features. LED Driver Based on UCC28060 Interleaved ACDC Single. Stage Flyback. Tony Huang. Power management products/Field Applications. ABSTRACT. UCC28060 can be implemented in an ACDC single stage solution with transition mode interleaved Flyback topology. This note will discuss the design considerations and Page 1. SLUA6. 25.
