Part Number: UCC28781EVM-053 Other Parts Discussed in Thread: UCC28781 Hello TI,
Could you please explain how does Q100 work and what is it for?
Can it be replaced with BC807-25LT1G ?
Thank you in…
Part Number: UCC28781-Q1 Other Parts Discussed in Thread: UCC28781EVM-053 HI TI,
We are building a board based on UCC28781EVM-053 where only DC input is used.- Does that mean we should not include the marked block, also ground the XCD signal?
Part Number: UCC28781-Q1 Other Parts Discussed in Thread: UCC28781EVM-053 , Hello TI,
We are doing calculations on a design that should have 650-900Vin and 68V 0.6A output. I have never seen transformers with inductance in 10mH range. Is our calculation…
Part Number: UCC28782EVM-030 Other Parts Discussed in Thread: UCC28782 , , UCC28781EVM-053 This EVM states 90Vrms minimum input voltage, what happens at lower input voltage? Can this IC be used at 60V input?
Part Number: UCC28781 Other Parts Discussed in Thread: UCC28782 , , UCC5304 Hi,
I want to design a with following specifications:
Input voltage: 30V-200V (if too wide, can be made in two options, 30V - 90V, 80V - 200V)
Output voltage: 5V 6A
Yes, the IC can be used to control a ZVS Flyback converter with a 40V-900V input range. I am assuming that this is a DC input, not AC.
The IC is not connected directly to such voltages, however, it has signal inputs to which scaled signals…
Thank you for the additional information. It is going to take me a little while to analyze it all and provide some meaningful guidance.
But let me address your last question first. I agree with your RDM calculation and you do have a…
