Other Parts Discussed in Thread: TPS54425

Hi,

We are planning to use TPS54425 to convert 12V input to 3.3V output. How much maximum continous current it can support at 3.3V and what would be the efficiency.

TPS54425 EVM is designed for 1.05V output but at max load current of 2A. Why not at max current rating of 4A and what was the limitation to design for max of 2A?

Regards,

Veera.
