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.
Because…

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 Regards…
Hi
(1) For the minimum VCC voltage, you need to make the VCC above UVLO_on. For UCC2813-0, the UVLO_on is 7.2 V.
(2) Here are differences for different part number from UCC2813-0 to UCC2813-5. They have different turn on voltage of UVLO.
(3) The maximum…
Part Number: UCC2813-0-Q1 Hello,
I am planning to design a flyback converter with the following specifications:
Vin: 9-18V
Vout: 300-500V
Output power: 20-40W
Operating frequency: 100KHz
Please clear/provide suggestions for the following points:
1. UCC2813…
Hi Michael,
The UCC28C4x and UCC2813-x devices are normally used in secondary side regulated designs which use a TL431 and opto-coupler to feedback the error signal.
In these designs it should be possible to get better than +/-5% total regulation of the…
Part Number: UCC2813-0 Other Parts Discussed in Thread: UCC3813-0 , Dear, Sir.
My customer is considering to replace from UCC3813DTR-0 to UCC2813DTR-0,
also from UCC3813DTR-1 to UCC2813DTR-1.
I tried to read out the datasheet, but following are not clear…
Other Parts Discussed in Thread: UCC2813-1 , TL494 Hello everybody;
I need a low-power dc/dc converter with high isolation voltage between the primary and secondary-side of the switching transformer. The input voltage is 15V while the output voltage equalizes…
Part Number: UCC2813-2 Hi Experts:
My customer is using the UCC2813-2 for the power design , the turn on threshold is 12.5V, however, the maximum rating of VCC is 12V , so I have two questions:
1) The start up voltage should be above the 12.5V which will…
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.…
