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
Currently,…
Part Number: UCC28781 Other Parts Discussed in Thread: UCC2897A Hi team
Customer wants to develop 200W AC-DC with Flyback, 85V~264VAC standard input, and due to low-cost consideration, they want to use UCC28781 to finish this 200W power without PFC stage…
Hi Sam,
The UCC28050 does not have any kind of simulation model available, so the only way to run a simulation with both controllers is to manually construct your own Simplis device model for the UCC28050 using its datasheet block diagram, parameter table…
Part Number: UCC28781-Q1 Other Parts Discussed in Thread: UCC28781 , , UCC28782 Hello,
Pout <400W is possible to achieve with UCC28781 IC, with Single stage PFC Forward converter?
Is Simulation model available for this IC?
Thanks

Part Number: UCC28780EVM-021 Other Parts Discussed in Thread: UCC28781 , UCC28780 Q2 (P/N BSS126H6327XTSA2) of UCC28780EVM-021 has drain-source on-state resistance around 300 ohms (maximum 700 ohms). Could use use CPC3960 which has maximum on-state resistance…
Hello,
What is your efficiency specifications?
The design you did was for a standard output rectifier. You increase the efficiency by using a synchronous rectifier FET by 3 to 5 W. This would improve the efficiency by 5 to to 8%. You could use the UCC24612…
