Part Number: UCC2813-1 Tool/software: Hello
Could you, please, explain how overcurrent protection works. The overcurrent current comparator has a 1.5V threshold. But how voltage on CS pin can reach this threshold if current limiting circuit will limit…
Part Number: UCC2813-1 Tool/software: Hello,
Datasheet for UCC2813 has limited value for Vcc current, but it does not say if it is RMS or Average value. As this current has pulsed shape, the difference between RMS and Average is very significant. Could…
Part Number: UCC2813-1 Hello. Datasheet has parameters for "Current sense"(page 6). Which element on the Block diagram (page 9) do these parameters refer to?
Thanks
Part Number: UCC2813-1 We got a problem with accurate calculation/simulation of UCC2813-1 oscillator frequency.
We found that the frequency from formula 1 (datasheet) is perfectly coincide with simulation but does not coincide with Fig.18 (datasheet…
Part Number: UCC2813-1-Q1 Hello,
What is the value in the WEBENCH Power Designer if it not follows the obvious design limits.
The compensation network is 1nF and10k for all cases, is that really so simple?
Part Number: UCC2813-1 Hello,
Regarding to Absolute Maximum Ratings on UCC2813-1, my customer is asking some question.
They are understanding that even if Vcc exceeds 12V(Absolute Maximum Ratings), it is no problem when Icc does not exceed 10mA…
Part Number: UCC2813-1-Q1
Hi,
We got a question from the customer about UCC2813-x-Q1. Could you help us?
[Question] They are considering using spread spectrum clock for external clock synchronization. Are there any concerns for this usage?
Best…
I have not tested using the current method but I have done extensive testing of CISPR 25 and CISPR 32 both CE and RE. There are many E2E discussions detailing the use of ferrite beads, PCB stitch capacitor, CMCs, DM filters and Y-caps...all used as EMI…
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.

Hello Alireza,
It is difficult to tell if that bobbin is designed to accept an EFD core just by looking at it. The shape of the bobbin appears to fit an EFD core shape, but only a datasheet for the bobbin will verify if its dimensions are correct for…
