Part Number: TPS1663

According to the datasheet of TPS16630, pin 19 and 24 is NC.

According to thte datasheet of the TPS16630 EVAL board, pin 19 is OUT and pin 24 is IN.

Which is right/wrong?

Hello Magnus,

The pin-out provided in the datasheet of TPS1663 is the final pin-out for production release of the device.

Currently; the pre-production samples (PTPS16630RGE) have pin out given the EVM user's guide(http://www.ti.com/lit/ug/slvubi9/slvubi9.pdf ) .[Pin24 is VIN and Pin19 is Vout]

You can leave NC pins floating.

NC pins (Pin20 to Pin23) are connected to GND on the EVM for enhanced thermal performance.

See picture below. Your recommendation is to leave pin 19 and 24 floating?
