Hi Sheng-yang-san,
Ok, I'll check with PL regarding I VSL(run) of UCC28631.
Yes, the PMP20495's indusctor is supposed to be surface mount inductor 74435571500 from Wurth, but in the photo L2 looks like bulky and different.
I didn't realize it is…
Part Number: UCC28631 Other Parts Discussed in Thread: PMP20495 Hi team,
I'd like to check one thing regarding UCC28631 VSENSE pin open or short pin-check.
Does VSENSE pin detect open if thevenin resistance of the divider RTH is <10kOhm and detect…
Hi Harish-san,
Sorry, my customer is referring to the diode connected to the output voltage. It is similar to the D2(DFB) of PMP20495 attached. Could you answer the above diode selection question again?
