Part Number: UCC28911 Hi team,
Referring to the application note of snva750, the Vbrownout = 43V at the equation (1). Could you give me comment on how to derive the value as 43V? The lowest input voltage looks to be came from 85Vac, and the datasheet…
One more questions about valley switch mechnisam. Below diagram is capture from UCC28911 datasheet.
Base on my understanding, when VDS drop nearby zero means MOSFET turn-on, and I marked three turn on cycle with red circle.
I don't understand what the…
Part Number: UCC28911 Other Parts Discussed in Thread: UCC28700-Q1 , UCC28700 We are developing a cost sensitive device that would be powered from a 48V/60V Lithium battery pack in an electric vehicle. Overall the main components of the device would have…
Part Number: UCC28911 Other Parts Discussed in Thread: LM5021 Hi team,
The parameters indicate that Vinmax=450V, but I could not see a confirmation of the limitation in the datasheet.
Is there any reason someone could not use this device up to 600V ? …
Part Number: UCC28911 Other Parts Discussed in Thread: UCC28730 , UCC28910 Dear TI Team

Part Number: UCC28911 Hi,
My customer is considering using UCC28911 because they require small solution.
Conditions are below;
VIN=AC100V
VOUT=2V
IOUT=600mA
Do you think that UCC28911 can output 2V?
If no, what is the cause of the lower voltage limit…

Part Number: UCC28911 Other Parts Discussed in Thread: PMP30605 , Hi team,
One of my customer can't buy motor BS64048CT used in reference design PMP30605 and can't find any specification of it. Could you tell us the turn ratio between Primary，Secondary…
Part Number: UCC28911 1. The Xcel calculator tool states that Macros are to be enabled; but I dont see any Macros in the calc tool when I open it, so is this a false statement or did the Xcel tool load improperly?
2. I am suspicious because the tool isn…
