Part Number: TPS54260 Other Parts Discussed in Thread: TPS54360 Tool/software: Dear TI experts,
we have in a TPS54260 inverting psu following the TI app note www.ti.com/.../slva317b.pdf
This schematic works until around 250mA of current drawn, then…
Part Number: TPS54260 Tool/software: Surge Test Fail at TPS54260 output.
Test waveform are open circuit voltage waveform(1.2/50us) and short circuit current waveform(8/20us).
When I finish test,power on Tps54260,it burned.
But I dont konw why.How to…
Part Number: TPS54260-Q1 Tool/software: Hi Expert,
My customer found the output of TPS54260-Q1 is 52V, not 0V, under the EFT test. Though he try add some Caps or TVS, but these methods doesn't work.
The schematic, test input waveform and output waveform…
Part Number: TPS54260 Tool/software: Hello, the batch of products produced by my factory recently includes material tps54260,
some of the marking have the TI logo like this ,some are not。 Is this a normal situation? Why this happening?
Part Number: TPS54260 Hi,
The thermal pad has been resized according to PCN# 20240402000.1.
Do I need to change the size from the Land Pattern listed on the Revision D datasheet? If so, what are the dimensions of the Pattern? Is it okay if I set the…
Part Number: TPS54260-EP Hi,
The Radiation & Reliability Report for component TPS54260MDRCTEP , found in the technical documentation section, shows the report for another device when opened.
Can you please verify it?
Thanks.
Part Number: TPS54260 Greetings, I am designing a Power Stage of PCB, In my past designs I always pour a GND to thermal pad of TPS54260 as mentioned on the datasheet and no problem with it. But In my another design I have forget to pour GND at thermal…
Part Number: TPS54260 Hi, I am currently using the old "DCDC_TPS54x60_CALCTOOL_v1.xls" provided by TI to design a TPS54260 power supply. I was just wanting to confirm what the 'lf' value represents on row 137 of this calculator? It looks like it is just…
Part Number: TPS54260 Hi
We had our PCBA manufacturer fit the wrong resistor to the RT/CLK pin 28K instead of 287K.
I understand this would put the switching frequency well over the maximum.
It appears the the chip is running in eco-mode and the output…
