You will have issue to use UCC2871x in buck mode based on PMP9087 structure as 5V output is lower than UCC2871x VDD UVLO point. The controller won't even…
Part Number: PMP20122 Other Parts Discussed in Thread: PMP12082 , UCC28C42 , PMP10833 How can i Convert the Same Design into a 3 Phase Input ? Can i add the 3 phase using diodes ? Just like the refference design of your Poly Phase metering design ?
And…
Part Number: UCC28710 Other Parts Discussed in Thread: PMP20122 Hello,
We are using circuit described in PMP20122 REV B. This is non-isolated universal input AC/DC Converter for output of 12V 500mA. After populating the components we are getting output…

Hi Luca,
Since the GND of UCC28C45D is at the switch node, the output voltage is only feeding to the feedback resistor divider when the freewheeling diode (D5) is conducting current. That voltage is holding up by the capacitor on the feedback resistor…
