TPS25740 Datasheet Typographical Error

Other Parts Discussed in Thread: LM5175, TPS25740

Hi,

On page 47 of the TPS25740 Datasheet, in Figure 56, the capacitor next to the DITH output of the LM5175 has a value of 0 Ohms. The component is highlighted in the picture below.

What is the value of that capacitor suppose to be, or should it just be shorted to ground in this case?

Thanks,

Ethan

Also just noticed the lack of a connection at the GDNS port on the TPS25740. Should there be a connection from the port GDNS port to the Source terminal of the power MOSFET (CSD17579)?

Hi Ethan,

Thank you for your diligence and for pointing these items out.

1. For the LM5175 DITH pin, the LM5175 datasheet shows the following. We do not use the function and so connected it to ground.

2. Do you mean Figure 39?

If you find other ambiguities, please use the submit feedback link at the bottom of even #'d pages of the datasheet. Your input will go through our digital marketing group and will be logged so that those items get implemented in the next update. Use Google Chrome if Internet Explorer does not work (I had trouble with IE 11).

Eric,

Appreciate the response. In regards to my second question, it was in the same figure (Figure 56. DC Power Source, page 47) that I referenced in the first question. Figure 39 shows a connection from GDNS to Vbus while Figure 56 shows no connection.

Thanks,
Ethan
