Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Part Number: PMP8787 Other Parts Discussed in Thread: UCC28700 the file mentions this design sues high efficiency with the quasi-resonant mode, are all the plots in the test results using this mode?
We'd need to be able to have the input be a half-wave rectified…
Hi Rafeeq
Oops - I neglected to answer that part of your post - Transformer inductance is the magnetizing inductance of the primary winding of the transformer. It's not very clear but the term "Inductance" is the inductance of the output inductor.…
Hi Henk
The short answer to your question is - YES - here's a markup of the schematic showing where the output of the Flyback goes. BTW - I'd suggest you use the UCC28951 instead of the UCC28950
The UCC28951 device is an enhanced version of the…
Hello Harini
Regarding your earlier post - I added the potential divider from CS to GND rather than VREF to GND as shown below. Both connections will affect the delay times but the one to CS will give a delay which is inversely proportional to the current…
Hello Kaji-san
You are correct the VREF of the UCC28070 isn't really strong enough to supply current to the ISO7710 device. It has a maximum rating of 2mA and we recommend that the current be kept below 500uA. This is enough to feed the potential divider…

Currently, my client is planning to develop the specification of AC 220V Input / 2.5V, 450A Output.
I think the circuit should be composed…
Hi Sir / Madam ,
This is vengad here from Avnet India , I am doing the AC/ DC Adopter design based on PMP8787 Ref-design for one of my customer . can you please share the PMP878 ( Flyback RLTI-1084 Renco Electronics) Transformer detals ?
regards/
