  • UCC28180: UCC28180 pfc controller for 400hz 115V input power

    Part Number: UCC28180 Hi, We are planning to use this UCC28180 as a PFC controller before a DC-DC converter to step down finally to 28V,8A. Will this PFC controller works with an input of 115V,400HZ AC input . Any other recommendations or integrated…

  • UCC28180: UCC28180 ISENSE DIODE SELECTION

    Part Number: UCC28180 Hello Experts , I am working on 650W PFC based on UCC28180 . Need help to understand what happen if ISENSE pin Diode is BAT54HT1G , Current sense resistor =15 mohm , Rsense = 220 Ohm . Is BAT 54HT1G is wrong choice ? is this cause…

  • UCC28180: UCC28180 ISENSE Divider & OCP Threshold

    TI Thinks Resolved
    Part Number: UCC28180 Hi TI Team, I am using the UCC28180 in a CCM PFC design. I added a 300-ohm resistor(DR262) as a voltage‑divider element before ISENSE (pin 3) to attenuate the shunt‑voltage. The purpose is to effectively raise the OCP current threshold…

  • UCC28180: UCC28180 - PFC Converter Bulk Capacitor Issue

    Part Number: UCC28180 Hello, I try to obtain a 800V output with 400W DC/DC converter. The output load is just a 133uF capacitor. So, 400W output power comes from just charging and discharging this capacitor between 800V and 0V. I shared the circuit…
