Part Number: UCC3817A Other Parts Discussed in Thread: UCC3817 , UCC28064 , UCC28180 Hi
I would like to ask if this IC UCC3817 is capable of operating at 400Hz line frequency without any trouble and meeting DO-16 harmonics standard.
Do you have…
Part Number: UCC2817A Hi,
I have designed the PFC stage using UCC3817AD and want to replace it with UCC2817AD as the ambient temperature around the IC is more than 70C. Have already completed all the design evaluation and testing and is ready for…
Part Number: UCC3817A We are using the UCC3817AD in a PFC with Vac range from 80-264V. At max rated load (130W in) the AC line current breaks up into chaotic noise with an extreme amplitude of ripple (roughly 17 - 20KHz). This noise starts near the crest…
Part Number: UCC3817A Hello guys,
One of my customers is designing their PFC circuit using UCC3817A for their next products.
They know there is a calculator for UCC3817A peripheral parts calculation which works on MathCAD software.
But they don…
Hello Kazuya Nakai,
Gid is set by the equation :
Vout is the fixed output voltage
Rsense is the current sense resistor
L1 is the boost inductance
Vp is the ramp peak to peak voltage (3V )
fc is the desired crossover frequency
Because all…
Part Number: UCC3817A Other Parts Discussed in Thread: UCC3818A Hello guys,
One of my customers is evaluating UCC3818A for their new products.
They tried to read TI MathCAD file TI prepared by MathCAD trial version because they want to adjust some…
Other Parts Discussed in Thread: UCC3817A , UCC3817 , UCC3818 Posted on Behalf of a Field Engineer,
I see that you have both a UCC3817 and UCC3817A device which should I use?
Other Parts Discussed in Thread: UCC3817A Hello,
The customer download the UCC3817A Mathcad file from Ti web site, but I couldn’t read it with Mathcad latest version. Is it possible to get the updated file.
UCC2817/17A, UCC2818/18A, UCC3817/17A…
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…
Hi Adam,
In a setup like figure 11 in the datasheet my customer wants to know the abs max on the pin. I do see that this configuration is only for UCC3817A, but are you still able to provide a value?
Thanks,
Michael
