Part Number: UCC28782 Hi,
I have tested PMP23224 board with an output of 8.4V, 3A it is working fine.
After that I have changed layout replaced with all the 0402 componnets with 0603 size
as well as leade MOSFETs with SMD.
Now problem is when…

Happy New Year: thnx for the excellent support last year ...
We are redoing the 65W "open frame" converter with different DC inputs.
EG: 400 max DC to 160 min DC
We entered what seems like useful…
Part Number: UCC28782 Hi all,
with respect to PMP23224 demo circuit, I would like to set CC limit at 3A only.
I have traied R63 increses upto 500 ohms. But current limit is not changing.
and also incresing the R65 value upto 10.2kohms.
PLease…
