Part Number: UCC28710 Other Parts Discussed in Thread: UCC28910 Hi all,
This is a high-voltage BUCK made with UCC28710. UCC28710 works in DCM mode. The input 30-150V, output 12V/3A.
1、I would like to know how this frequency is calculated. Is the calculation…

Hi,
We are developing a flyback converter with 85-265Vrms 50Hz input to 12V, 1.5A output using the PSR IC UCC27812D. But during our tests we observed that the output is oscillating…
Part Number: UCC28730 Other Parts Discussed in Thread: UCC28710 , , UCC28711 Team,
Is there a difference in the current limiting capability of UCC28730 vs. UCC28710?
It looks like the parametric comparison table calls out an additional current limiting…

Customer requested DFMEA report for UCC28710D. Can you please help.
Thanks Shinu.
Part Number: UCC28710 Hello,
I am trying to get our UC28710 design to work with a new transformer, Wurth 750312170 , but I can only get the chip to begin switching when Vin_Bulk > ~180V. I would ideally like to use input voltages down to ~100V. I used the…
Part Number: UCC28710 Hi Team,
We have selected UCC28710 part no for 1 Phase or 3 Phase Power supply with 24V/3 A output, so in proto type we are facing audible noise as per low descriptions , when we have turn on at load so audible noise observed
please…

Part Number: UCC28710 Hello,
I would like to calculate some parameters on UCC28710 and must make sure a behavior of frequency at some load conditions.
My question is:
a)In my understanding, the below condition is needed for starting constant-current mode…
