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.
Because…
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 Regards…
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
(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: UCC2805 Other Parts Discussed in Thread: UCC2813-5 Hi,
Good Day.
Customer would like to ask you a few questions that arise in the framework of a new design that currently is being developed.
The new PSU design is indented for automotive…
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…
