Part Number: TPS5405 TPS6406 is a similar buck controller and a private version for special customer, customer found TPS6406 restart twice(LED flickered twice when input power down), and they worried about this would cause the EEPROM fail.
Part Number: TPS5405 I would like to be able to disable (enable) this device. There is little explanation of enabling the device. I think I can use the SS pin but there is no example or description of this feature (if it exists). My thought is to pull…
Hi Sarma,
If P2P is must need for this case.
I think we don't have better solution here, while we have one fixed 5V output version TPS5405 which is the same gen of this part.

Other Parts Discussed in Thread: TPS5405 , TPS54260 , PCM1794A A couple of the calculations on the TPS5405 datasheet are confusing me; either I'm going wrong somewhere (probable) or there is an error on datasheet.
Firstly, in equation (1): If I plug…
Other Parts Discussed in Thread: TPS5405 I have a question about TPS5405.
Question is about frequency set by ROSC pin. What frequency set by ROSC pin to ground. It is different number on datasheet and EVM User's Guide.

Other Parts Discussed in Thread: TPS5405 Hi,
I need to select a buck converter
Input = 24V +/- 5% tolerance
Output= 5V, 600mA maximum,
I was thinking of using TPS5405 , but going through the datasheet i find there is a pulse skipping mode with threshold…
Other Parts Discussed in Thread: TPS5405 Hi all,
Is there any way to define the TPS5405's switching frequency using Rosc resistor so it remains fixed? I have placed 100k resistor and I have around 270kHz switching frequency when I measure it across Schottky…
What is the power conversion efficiency of this chip at 24V (eg. at 1 Amp) ? The datasheet only lists efficiency at 12V (around 90% @ 1A). I need to know that there will not be too much heat to dissipate.
Part Number: TPS5405EVM Hello team,
Can you please tell me the physical size of this evaluation board, TPS5405 Evaluation Module ? I cant find it listed anywhere on documentation and the design files are not on the hardware folder.
Thank you!

Hi JC,
Kindly note that we have updated this BOM for TPS5405 EVM , to add this terminal block .
Thanks a lot for your pointout and sorry again for this inconvenience.
