TPS62130A-Q1: Duplicate pin 7 in datasheet

mjones5033
Prodigy 10 points
Part Number: TPS62130A-Q1
Other Parts Discussed in Thread: TPS62130A

In the datasheet for the TPS62130A-Q1, in the pin function table on page 3, pin 7 is listed twice with two different functions: LOG (internal logic) and FSW (frequency select), with contradicting descriptions.  Elsewhere in the datasheet, the pin is exclusively referred to as FSW and I can't find any other mention of a LOG pin.  Further, the non-automotive version of this part (TPS62130A) does not have any reference to LOG.  I'm assuming that the reference to LOG in the TPS62130A-Q1 is thus an error, but I would like confirmation.  Thanks.

    Thank you for highlighting this. It should be fixed in a new revision of the datasheet.
    You can use the Switching Frequency Select Function (FSW) as described in the datasheet. The option to lower the switching frequency did not exist in a previous version of the device.
