Hello w w2,
Thanks for reaching out and using the TPS40210.
Are you referring to the ringing on the switch node? The ringing of the switch node id due to parasitic components of the MOSFET and the switch node.I am assuming that the 33ohm and 4.7nF…

Hi
About attachment circuit: This design is basically sepic converter with two separate inductors. Normally the resonance capacitors between the two inductors are only ceramic types.…
Hello Jerry,
A FlyBuck may not reach 12 watts that you need. A classic Flyback would be better.
The reference design tool is very helpful in these situations. It can help identify designs that are close to what you need and which TI devices would…
Hi Brigitte,
The input is 24V，throw TPS41020 Boost to 115V，the test video show that 100mA/200mA Load,the output voltage drop down and show unstable.
Customer want us help to check the schematic and pcb layout,pls find attachfile.
Thanks

Hi Thomas,
Thanks for using the e2e forum and designing with the TPS40210.
Unfortunately, the editable excel sheet is rated as NDA restricted, so I cannot hand it out that easily. We have other flyback compensation tools, which are more general and…
Hi Zhang,
Sorry for the delay. Yes, we have several literature pieces on design stability and compensation. Please refer to the following: https://www.ti.com/lit/an/slva381b/slva381b.pdf

Hi,
I've attached the 2013 User's Guide for power products. Starting on page 53 you will find a selection of PWM controllers. many of these teh frequency can be varied according to external criteria.
As an example if you use a UC3842 it is a simple…
Gary,
Most any of our power controllers with dual output capability will provide the control. See attached document starting at page 50 with the dual output controllers on page 53 and 54 and choose what features you want.
Regards,
John
