TPS54308: Power supply design

Jingtai

Part Number: TPS54308
Other Parts Discussed in Thread: TPS54302, , LM25005, ADS6125, DAC8760

I ordered based on my design but TPS54308 is not available due to out of stock or other reasons. I selected another option TPS54302 but the web page is frozen as this and 'save name & note' doesn't work. I have tried several times.

Hi Jingtai,

I tried to open the Webench model for TPS54302 and it worked. Have you tried to select other input voltage or output voltage? For the stock issue, I will talk to our marketing guys. Besides, pay attention to the difference between TPS54308 and TPS54302. TPS54308 is a fixed frequency part and TPS54302 will enter into skip mode under light load.

Best,
Anthony

When I checked my design in fact it has been saved. I have selected LM25005 that is on stock. WEBENCH prompted that TI will forward to Digikey processing. I'm waiting for Digikey.

Are you comfortable to tell us what is application for this device and how many pcs of sample you need? What is the estimated annual amount for massive production?

It is for signal processing that includes ADS6125, DAC8760 and Launchpad. I have ordered two pieces already. I'll make prototype for test and it takes time to start production.
