Part Number: UCC28780 Other Parts Discussed in Thread: PMP30631 , , PMP , TL431 Dir Sir/Madam,
I have successfully simulated the design on the kit .
Now I want to change the design to output 5V ~ 6A.
Simple iteration of the ratios reported in the PMP30631…
Part Number: PMP30631 In PMP30631 R5 feeds current from a 27V regulated supply to an 18V regulated supply. Pdiss = (27-18)^2/100 = 0.81W. The part in the BOM is specified as 0.25W. I would expect this resistor to run exceedingly hot but the thermal images…
For 110V DC Input, a power converter would be required at input of TPS2663.
For 70W power: you can consider reference design PMP30631.1
For 100W power, you can consider reference design PMP7453 .
The circuit described in App note :…
