Part Number: UCC28056 Hi,
The UCC28056 has an Over voltage protection (OVP1 - 428 V & OVP2 - 450 V) as per the datasheets provided in the website. I would like to know at what input line voltage this output over voltage condition may occur? and up to…
Part Number: UCC28056 Hi,
I have designed a PFC circuit using the UCC28056A. When I power on the circuit, the output voltage oscillates. When looking at the current on the shunt resistor, I can see that everytime the converter starts switching, the current…
Part Number: UCC28056 Other Parts Discussed in Thread: UCC28051 , TPS92314 Hi experts,
My cusotmer considers to use a single-stage PFC-flyback controller to convert outlet AC into 15V-2A DC for auxillary power supply.
As shown in the image above, I…
Part Number: UCC28056 Hi
I'm Jongyoon.
I'm Currently designing a PFC with UCC28056 and have some questions regarding it.
First, my specifications for I/O is as follows :
Vin (AC) : 198 Vrms ~ 242 Vrms
Pout : 200 W / Vout : 400 V
Here is my q…

A customer wants to make an AC/DC with PFC design using this device.
Got a curcuit by WEBENCH-CIRCUIT-DESIGN tool as attached. But it has no input on the THD requirements and cannot…
Part Number: UCC28056 Other Parts Discussed in Thread: TPS92314 Hello,
i am now trying for a long time getting the UCC28056 to work, it's basically operating fine and performing PFC action. But measuring the switch waveforms i notice that valley switching…
