Part Number: TIDA-00702 Other Parts Discussed in Thread: TL431 Tool/software: Hi, experts.
I have a question about sensor design.
For isolated converter control, all most of engineer use either a TL431 + optocoupler or Isolated sensor.
So, the controller…
Part Number: TIDA-00702 Other Parts Discussed in Thread: UCC28811 1) I want a quick clarification what is the power factor of this Supply module. Whether PFC can be incorporated in this module.
2) How the feedback elements are chosen. Please provide with…
is there an article about how how to select Coupled inductor? why L1 is 5.5mh，why L2 is 20mH. Now I want to Let the 4-level EFT decay below 10V, or below 0.5V, how to choose the common mode inductor? Is it possible to achieve attenuation with a common mode…
Eric,
This design is somewhat close: www.ti.com/.../TIDA-00702

Part Number: UCC28740 Other Parts Discussed in Thread: TIDA-00702 , Hello black magic wizards.
I have seen a lot of application notes concerning layout guidelines for switch mode power supplies. Most of them based on a 2 layers PCB stackup.
In our design…
Hey Scott, Thanks for your interest in TI! We have a reference that is very close to your specifications, we recommend basing a design off of this: www.ti.com/.../TIDA-00702 Use that design along with this app note to help debug any issues, should they…
Guifre,
First of all, for that power level (48 W), the original transformer inductance of 1.57 mH does not sound correct - that's far too high for such a high power level. In fact, even the value of 560 uH that you actually used sounds too high. Did…
