Part Number: UCC28740 Other Parts Discussed in Thread: UCC256302 Hello everyone,
considering power supply stabilization and power stage bode plotting the most covered situation in literatur are controllers, which feature "voltage controlled" feedback…
Please refer the application note as below. page 8~page 9.
You may need to modify the Rsnub to reduce spike.
Part Number: UCC28740 Hi Team,
For the jitter application of UCC28740, could your help with the following 2 questions?
1. When applying jitter frequency to improve EMI, comparing with non-jitter status, will the load regulationof the non-feedback circuit…
Part Number: UCC28740
I found our UCC28740 have Brown-out Protection function.
if we want to do a monitor/indicate of such Brown-out application.
how do we realize the indicating function? any solution we have?

I want to make a design for Three phase AC to 5 VDC, so followed this reference PMP30164. Please verify the attached circuit and let me know your feedback on this. Also please clarify…
Part Number: UCC28740 Other Parts Discussed in Thread: LM5021 Hi Team,
There is a good new that we could DIN TI product!
Customer is looking for the replacement of NCP12400EAHBB0DR2G (P2P would be better )
1. Please help suggest TI solution, THX
UCC28740 build frequency dithering inside to improve EMI. So if the dead-time that IC detected at certain load condition, which is the boundary of valley detection, this phenomenon could happen.
The circuit does modulate the peak current to modulate the frequency. However, your output current should not be showing the different in peak current. This AC current should be going through your output capacitor. This different in current may…
