I am designing isolated DC to DC converter for EV 2w/3w automotive application with following specification.
Electrical: DC-DC Converter (72V to 12V) Input Voltage: 72V…
Part Number: UCC28781-Q1 Other Parts Discussed in Thread: UCC28781 , UCC28782 Hello,
I am going through the design steps in the datasheet of UCC28781-Q1 to design a AC - DC converter. But I am stuck at VBUR calculations in 8.2.2.4 which says
"The procedure…
Part Number: UCC28781-Q1 Other Parts Discussed in Thread: TL431 Hello TI,
Would it be a good idea to place the voltage feedback signal "VOUT" after the L403? Currently its at before the CM choke but it complicates the polygon pours + spreads the noisy…
Part Number: UCC28781-Q1 Can R37, R38, R20 be replaced by a single 19.6k resistor? What purpose do D11 and D12 serve? What consequences will occur if they were to be removed?
Thanks
Part Number: UCC28781-Q1 Other Parts Discussed in Thread: UCC28782 , UCC24612 , UCC28781 , UCC5304
Can a SR controller be used with this IC? I am thinking of UCC24612 since its suggested for UCC28782 in Webench design tool. Or is it a must to use an isolated…
Part Number: UCC28781-Q1 Other Parts Discussed in Thread: UCC28C56EVM-066 , UCC28781 It seems that >1kV depletion nmos costs a fortune, therefore i am looking for other possible solutions.
Maybe a zener to drop 30V via high voltage resistors? Problem…
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: UCC28781-Q1 Other Parts Discussed in Thread: UCC28782 ,
Input 350VDC out from a active PFC.
Output 65V
now my Problem:
in Webench i can't customize the ratio of the Trafo, i can search and there are only fixed ratios to select? in additi…
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?
Thank you…
