Other Parts Discussed in Thread: UCC24612 We design and develop a 100KHz drive flyback converter power supply with 100V AC 50/60Hz input and 12V 6A output.
In order to configure the secondary-side synchronous rectification, the circuit was configured…
Part Number: UCC24612 Hi team,
Could you please tell me why CCM/DCM/QR Flyback is not mentioned in the recommended topology of UCC24612-2?
Best regards,
Hi Kobayashi-san,
I am glad that it is getting clearer. Trying to explain it to you is also helping me to understand it better and helping me to explain it better. I wish I had more time available to draw some diagrams. That would really help a lot, but…
Hello Kobayashi-san,
I'm sorry, I am not exactly sure of the answer. I think the off-time blanking in point 3 is based on Toff_max being set.
The datasheet specifies that Toff_max = 3.68us, and I believe that that includes the total 2.2*Tring time allowable…
Part Number: UCC24612 Tool/software: Hi team,
The UCC24612 determines the inhibition period of proportional control based on the conduction time of the previous cycle, but how does it determine the first pulse?
Does it control to Vthreg-50mV after TONblank…
Part Number: UCC24612 Tool/software: Hi team,
I have two questions,
1.I have illustrated the transition of the proportional gate drive inhibition period. Is this understanding correct?
2,I have illustrated the timing of changes in the VTHREG threshold…

Hi,
Based on the evaluation board schematic and layout we have designed the schematic and layout for our custom board. The mosfet we are using is BSC061N08NS5ATMA1. What we are experiencing is that the SR starts and…
Part Number: UCC24612 Other Parts Discussed in Thread: UCC28782 , Tool/software: Hi team,
Is the conduction period from the previous cycle stored forever?
When returning from a long off period, is the previous conduction period stored?
Best regards,
Hello,
You are correct that shorter traces are better. You will add roughly 10 nH of inductance per inch. So shorter is better.
From your hand drawing you sent of the layout it looks like the traces from the UCC24612 to the FETs drain to source could…
Part Number: UCC24612 Hi team,
I have question related to Adaptive Blanking Time of UCC24612.
Following the datasheet, there is Adaptive Blank Time function which prevents false turn-on of the device occured by DCM ringing. It seems the blank time is…
