Hi TI Team,
I am looking for a Non-Isolated HPF Low THD CV supply solution for BLDC - Ceiling FAN application which can handle up-to 60W. I have got the reference of UCC28810/11 which can work in Buck CV mode.
I have attached schematic based on UCC28810/11 which is working in fly-back topology now I want to convert this into Non-Iso Buck topology so for that I have below query, which require your comments :
1.) For Non-Iso Buck solution do we need to connect optocoupler as well, please confirm.
2.) I wanted to know what is the function of Q2 and Q3 (refer attached schematic) ? Why it is connected to TZE ?
3.) If possible please share Non-Isolated Buck schematic based on UCC28810/11 for the reference purpose.
Regards,
Rishiket Kumar
