Part Number: TPS542A52 Hello team,
I have two questions about PFM mode.
1. In datasheet 7.4.1, for the application of 5V input, PFM enabling is not recommended. Can you explain more detailed about it? What happens in case of the low input voltage? Does…
Hi David,
Thank you for your support.
Is it okay to use the 0E on the opposite side of the IC TPS542A52 for connecting the PGND and AGND. . Would there be any issue due to the transition from the bottom to the top through a Via?
Part Number: TPS542A52 Hi, I designed PCB with TPS542A52 and it does not work properly. When power turns on, output goes to 5V but when we connect some load to it (like 100 mA) it immidiatelly goes down and after load is removed it does not recover to 5V…
Part Number: LM61480 Other Parts Discussed in Thread: TPS542A52 , LMK5C33216 , LMX8410L Hello,
Please advise the maximum force to be applied on the following IC packages, since it appears from the thermal simulations that adding a TIM material will help…
Other Parts Discussed in Thread: TPS542A52 hello, I try to use PSpice for TI to simulate TPS542A52's circuits which are not included in PSpice's library, and i got the video "PSpice fot TI: 3rd Party Model Import ". but i still can't understand what shall…
Hi Khoi,
TPS542A52, TPS542A50,TPS51397A , TPS56C230, TPS54A24 and TPS53319 can all do the job.
You can user TI's WeBench tool to design and get the full BOM.

Part Number: TPS542A50 Hello,
The pinstrap values for several functions of TPS542A50 are different between the datasheet (rev Dec 2021), Webench, and the Design Calculator. For instance, datasheet table 7-1 (R_FSEL) shows 7.5 kohm = 400 kHz, but Webench…
