Part Number: TPS543C20A
Other Parts Discussed in Thread: TPS543C20, , TPS543B20

Hi,

In my board I have 2x syncs TPS543C20RVFR, can I replace it with TPS543C20ARVFR without problems?

Or I need to do a few tests before?

From the datasheet I saw that the only changes are the input voltage (4V-14V to 4V-16V) and (Integrated 3/0.9-mΩ Stacked NexFET Power) to (Integrated 3.4/0.9-mΩ Stacked NexFET Power)

I'm using 12V input.

Hi Shay,

For operation at 12V input, TPS543C20A and TPS543C20 are interchangeable without problems.

Best regards,

Britton

Hi Shay, the only other part with the same footprint as TPS543C20/A is TPS543B20. Please place an order with your authorized distributor as soon as possible and, if you would like, you can choose to get a restock alert for specific part numbers so that you receive an email when the TI store gets more inventory.

Best regards,

Britton
