Tool/software: WEBENCH® Design Tools
Hi all,
I am developing an ESC (Ethercat Slave Controller) for an educational project. It will run in a harsh industrial environment (not automotive).
I have choose TPS560430YFQDBVRQ1 (among other reasons) because it is small and does not need external schottky diode.
In datasheet page 16 this link appears not to be working:
Not a problem, it is a new device. OK, I then follow instructions in page 15
I have prototyped some boards and got them manufactured but I am putting parts by hand so have soldered only power circuit at the moment, then put a load of resistor 220 Ohm to a LED. With 12Vin so far so good. But it does not work with 24Vin.
So my question is (whether it is possible to answer it in this conditions) in regarding to capacitor and inductor size limiting, what values will do it for 24Vin, 3.3Vout at 300mA?
Helpdesk have suggested me this forum will be the right place to ask for help, because I am working from home (as everybody else, I guess) and I have not a scope at my bench right now.

Hi Marco,
The link in datasheet page 16 is not working,we will report this issue to concerned team.
Below is the procedure to create Webench design for device TPS560430YFQ.
Step 1: Kindly use device TPS560430-Q1 product folder link mentioned below to access Webench panel.
https://www.ti.com/product/TPS560430-Q1?keyMatch=TPS560430-Q1&tisearch=Search-EN-everything&usecase=GPN
Step 2:Provide the required operating conditions and click "Open design" as shown in image below.
Below is the Webench design for condition reported.

Could you please try with inductor and capacitor value recommended by Webench and let us know if the reported issue persist.
Webench allows you to perform electrical simulation by clicking "SIMULATE" and export Webench design to CAD tools by clicking "EXPORT" as shown in image below.
Kindly revert back to us on any further queries.
Thanks and Regards,
Umayal
