Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Part Number: TPS54302EVM-716 Hi,
The DC-DC to inductor pattern is routed through the Bottom Layer. It seems to me that this pattern can be connected through the Top Layer. Is there any positive reason for this?

Part Number: TPS54302EVM-716 Other Parts Discussed in Thread: TPS54308EVM-876 , TPS54308 , TPS54302 Dear TI Team
On our PCBA's we use the TPS54308 Step-Down Converter for our 5V power supply. The PCBA and the Step-Down Converter itself gets powered by…
Part Number: TPS54302EVM-716 Other Parts Discussed in Thread: TPS54302 Hi Team,
As title, the TPS54302 on the EVM became really hot (106.9 deg C) at room temperature after about 3 minutes of test.
Is that within your expectation?
The simulated result…
Part Number: TPS54302EVM-716 Other Parts Discussed in Thread: TPS54302 Hello,
I am looking to use the TPS54302 in our next design. One of our main design goals is size. I am wondering if TI could provide the design files so I can easily compare size and…
Part Number: TPS54302EVM-716 Other Parts Discussed in Thread: TPS54302 Hi,
1. My customer used TPS54302EVM test (no change, all using EVM original setting), they found static load but switching Frequency is shift around 360kHz~400kHz,
Is it normal? If…
Hi Young,
The test setup feeds in 24V 1A max (CV/CC) with an Agilent U8002A, constant current load at 250mA. When the glitch happens, I can see the input current spiking and dropping back. I've added an additional 330uF capacitor close to the input and…
Part Number: TPS54302 Hi,
I have used TPS54302 in my below design. Can you please check/verify my below design circuit and the layout and let me know if it is fine?
The above layout is referred from the user's guide of TPS54302 Evaluation Module.…
Dear Shawn Nie,
Thank you very much for reply.
I have confirmed the operation and phenomenon with the evaluation board of TPS54302EVM-716.
Layout is TPS54302EVM-716.
Could you answer about question?
Best regard. Bob Lee.
Hi again,
Seemed that the issue was caused by unfiltered feedback.
Placed a 100pF from VOUT to FEEDBACK (across R20 in above schematic) and everything seems to works as expected.
Webench doesn't suggest this, and the TPS54308EVM-876 suggests not to…
