Part Number: UCC28730-Q1 Other Parts Discussed in Thread: UCC28740 , UCC28730 , UCC28740-Q1 Hi,
the data sheet of the UCC28740 suggests to use two capacitors to allow start up from high voltage for voltages above 700Vdc. Why is this not included in the data…

Hi Madam/Sir,
We want to design a isolated power regulator from a high DC input up to 300V.
I download a SLUC579_UCC28730 Design Calculator excel file from TI website , it is designed…
Part Number: UCC28730-Q1 Other Parts Discussed in Thread: UCC28730 Hi team,
I'm looking to use the UCC28730-Q1 on a 400VDC HV battery back-up supply to a low voltage, 12V rail. The 400V battery can face transients up to 800V, but the Abs Max of the UCC28730…
Part Number: UCC28730 Other Parts Discussed in Thread: UCC28700 Hello Ulrich:
We are all happy- project with UCC28730 proceeding rather well with 2 distinct flavors of products with many combinations of outputs...
But an interesting observation: see attached…
Part Number: UCC28730 Other Parts Discussed in Thread: PMP22557 , , PMP I require a 12V supply with a wide voltage input range. I have used the reference designs and recalculated values for 12V & 0.5A output current.
Can someone please double check…
Part Number: UCC28730 A curious question: if the DRV pin is clamped internally to 14.5 V with controlled current inside the chip, is it ok to clamp it to 5 v externally? Or 6v as well?
A whole lotta new ways become available if this is possible
Appreciate…
Part Number: UCC28730-Q1 Other Parts Discussed in Thread: TPS40210 , UCC28730 , LM25180 , UCC28910 , UCC28700 , UCC28911 Hello,
Can you confirm me if possible to use UCC28730 instead of TPS40210?
The price of TPS40210 is high and i need a driver with quasi…
Part Number: UCC28730 Hi
Please refer to below.
-SPEC-
Input: AC 220V
Output: 5V 0.6A
At output current 0.6a, it is maintained at 5v, but increases to 6v at no load.
Let me know if you know how to solve it.
Thanks
Part Number: UCC28730 Hi all,
I'm designing a 12V/2A smps using an ucc28730 and a former flyback transformer.
parameters are :
Vin min : 150V
Rs1 : 100k
Rs2 : 56K +10k var
Rcs :0.5R
Lp : 750uH
Np : 70
Ns : 9
Na :8
at 230V, it works but when there…
Part Number: UCC28730 Other Parts Discussed in Thread: UCC24650 Hello,
i have a question about the designing from the UCC28730. I would like to dimension an isolated FLY-Back circuit (DC to DC Converter as a auxiliary power adapter) with the ucc28730.…
