Part Number: UCC28631 Hi team,
Could you let me know the minimum TEMP TRIP (thermal protection shutdown temperature) of UCC28631?
Best regards, Kazuki Itoh
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…
Part Number: UCC28631 Other Parts Discussed in Thread: PMP20495 Hi team,
The VSENSE absolute min. voltage of UCC28631 is specified as -0.3V.
Is it allowed if the input current is limited <100mA
In order to protect the VSENSE pin from excessive negative…
Hi Kazuki-San,
Thank you for the reply. Any general purpose diode like BAV70-V should be ok for this purpose. Yes the diode voltage drop will be taken in account. But it should not affect the output voltage as during this interval, since the DRV output…

I designed a flyback using UCC28631. It does not startup and when I probe the SD pin I obtained this waveform. Please tell me the type of fault indicated by such pulse count. The flyback…
Part Number: UCC28631 Hi team,
My customer would ilke to estimate the junction temperature from the case top temperature of UCC28631.
Could you let me know how to estimate the controller power dissipation?
What datasheet current parameter should I use…
