Part Number: UCC28782 Other Parts Discussed in Thread: PMP22244 Dear TI Engineers,
I'm having some issues while using the UCC28782 chip and would like to ask for your advice.
My current circuit design references the PMP22244 structure. After calculating…
Part Number: UCC28782 Other Parts Discussed in Thread: PMP22244 , ATL431 , Dear TI Engineers,
Currently, I am using the reference design circuit of PMP22244, with an input of 220VAC and an output of 15V/2A. I have modified the sampling capacitor and…
Hi Abigail,
Thank you for reaching out.
Yes UCC28782 can definitely be used for this application. But it depends on the specifications of the customer as this is a high performance flyback which comes with increased cost, but provides highest efficiency…
Hello,
A 5 to 1 change on the output voltate is quite large. This will be a 5 to 1 change in duty cycle. I looked at the EVM and it looks like the maximum duty cycle at 85V AC is around 50%. So when you drop the output votlage to 5 V the duty cycle…
