Hi Steve,
Thank you for your answer.
I think I will follow your proposal to use a component derived from Unitrode UCx84y I already used several times.
I identified in your catalog several references: UCC2802, UCC2813-2, TL2843 and UCC28C43.
They look…
Part Number: UCC2813-3-Q1 Other Parts Discussed in Thread: UCC2813-2 , UCC2813-3 , Tool/software: WEBENCH® Design Tools Hi,
I'm attempting to use a UCC2813 chip to make a AC->24Vdc supply. I used WEBENCH to start the design and basically copied its…

As title, the target efficiency is 95% as higher is better since system design is fanless. Please check the electrical parameter as below.
Please recommend your solution and components power loss…
Hi Ajmal,
You can use pin to pin device UCC28C42-Q1, which has a Tj up to 125C.
Besides, you can also consider these devices such as UC1842, UC1842A,UC1843A, UCCx800, UCCx802, and UCCx803, UCC2813-0/-2/-3-Q,..........Maybe it needs a little circuit mod…
Hi Someno-san,
I cannot find a single channel PWM with a sync pin.
The oscillator on the UCC28C4x and UCC2800 family of devices can be sync'ed to an external source and both sets of device have variants that have duty cycles that can extend to 90%…
Other Parts Discussed in Thread: SG2524 , UC28025 , UCC28950 , UCC2895 Dear All,
I have two questions about IC numbers:
1) what is the meaning of prefixes, ie UCC, UC, SG, TL? ( for example SG2524 or UCC2813 )
2) what is the meaning of digits after prefixes…
Zhou,
For the UCC2813-0, UCC2813-2 & UCC2813-3, Dmax = 100%, for these versions OUT pin Fsw= Fosc.
For the UCC2813-1, UCC2813-4 & UCC2813-5, Dmax = 50%, implemented using an internal toggle flip-flop. So for these versions, Fsw = 0.5 * Fosc.…
