Part Number: UCC2818A-Q1 Other Parts Discussed in Thread: UCC2818
This is a block diagram of a CCM PFC. I want to understand the role of the feedforward constant block here.
This is the functional block diagram of UCC2818A-Q1. Can anyone explain how…
Part Number: UCC2818A-Q1 Hello,
I made a boost rectifier with UCC2818A-Q1, Vout 385V, 1kW.
Actually the IC is supplied with 12V from the external but I would like to supply it from mains as in the datasheet Figure 1 (pag.11).
I tried to made some auxiliary…
Part Number: UCC2818A Other Parts Discussed in Thread: UC3854 , UCC2818 Hello,
I ask if it is possible to use a smaller sense resistor (about 1/10 of the calculated value) and amplify the votage across resistor by means of a differetìntial amplifier made…
Part Number: UCC2818A-Q1 Hi Team,
I am Planning to use part UCC2818A-Q1 for 750W charger application. my input range is 170 to 270VAC.
Can you share the design calculation guidelines documents and design tool ?
Hi Madhura,
Since it's been over three weeks since our last correspondence, I assume you determined the wrong part number was entered in the E2E request and your question was ultimately answered. If your question was not resolved, please submit a new…
Part Number: UCC2818A-Q1 Other Parts Discussed in Thread: UCC2818
I am using the UCC2818AQ as a Power factor correction stage in a ballast circuit. The ballast circuit is a half-bridge inverter following the PFC stage. The ballast IC IR21592 has gone obsolete…

Part Number: UCC2818A Hi Support team
One of my customer's design is using UCC2818A as PFC controller
The current design has already have UCC2818A with another microcontroller. Is there anyway that can feed clock from MCU directly to UCC2818A? They…
Hi Avarind,
The UCC2818A-Q1 is an automotive-qualified version of the UCC2818A.
Please see this App-note about the differences between UCC2818A and UCC2818. By extension, the app-note will also apply to -2818A-Q1 and -2818. Differences between UCC2817A…
