Part Number: UCC28056 Tool/software: I want to design a PFC to meet the following requirements:
Input voltage : 240VAC Input frequency : 50Hz Output voltage : 380V DC Output power : 180W
Please provide a reference design.
Part Number: UCC28056 Other Parts Discussed in Thread: UCC28700 Tool/software: Hi!
I am wanting to design an AC-DC converter with this chip that will have the following topology:
AC IN (120V @ 60 HZ) > EMC FILTER > PFC (400V OUT) > FLYBACK (12V OUT)…
Yeah what ever your understanding exactly correct. but PFC UCC28056 is turning on But the flyback UC28782 is not turning on. after 30s of power interruption. is there any idea to get out of this issue
Our requirement is the time interval of 30s it sholud…
Part Number: UCC28056 Tool/software: Hi team,
I have a question regarding the operation of the UCC28056.
Is it acceptable to stop its operation by inputting an external signal to the COMP PIN and setting it to LOW?
Best regards,
Kyohei
Part Number: UCC28056 Tool/software: Initially loaded 4W output and get 398V output voltage. After changed the power from 4W to 8W then output voltage drop to 372V..

The customer Liyuan haina is debugging the 300W ACDC power with PFC (UCC28056A) + DCDC PSFB (UCC28950), now one issue for PFC is that at AC 250V input peak voltage with…
Part Number: UCC28056 Other Parts Discussed in Thread: UCC28051 Tool/software: I want to design a PFC to meet the following requirements:
Input voltage : 187-528VAC Input frequency : 45-67Hz Output voltage : 750V DC Output power : 180W
My plan was to use…
Part Number: UCC28056
Hello TI Team,
We are using the UCC28056CDBVR in our design and experiencing an issue where overcurrent protection (OCP) randomly activates during 3kV surge testing.
The problem is that OCP subsequently triggers OVP2 , which activates…
