PMP40934: The net label marked "TVSP" doesn't connect to anything else. Could it possibly be connected to an unused pad?

Part Number: PMP40934
Other Parts Discussed in Thread: TPS25762-Q1, PMP

The data sheet for the TPS25762-Q1 says the TVSP pin is used for setting the firmware via resistors by following table 9-3, but the PMP40934 reference design schematic doesn't show any firmware-setting resistors. Does the PMP40934 board route the TVSP pin to an unused pad for users to solder different resistors to?

Hi Stephen, it looks like the schematic uses the net label as just a label and electrically connected only to the IC's pin, and cap/resistor network configuration recommended in the datasheet. I can confirm this also on the layout documentation shown in the PMP product page.

Okay, I understand now. It must be the same for the "OUT" label as well, since it's the only label with that name.

Hi Stephen,

The PMP40934 choose the Index 0, it is open, so no need any resistor in that pin.

Best Regards,
