I have a design which assuming 12V input

and I need a 5V regulator to drive a Raspberry on board

do the IC TPS566238 able to do it?

Raspberry need 5.1V, 3A min

Hi Alex,

Surely TPS566238 can support 12Vin-5Vo-3A.

Do you need SS-pin or PG-pin? Auto-skip mode (higher light-load efficiency but larger ripple at light-load) or continuous current mode (lower light-load efficiency but smaller ripple at light-load)? We have a family TPS56623x for your selection.

thz for reply.

Since I do not think 3A is light-load, so I picking TPS566238 in my design

Hi Alex,

Of course 3A is not light load. But the processor may work in stand-by mode, loading current may be as low as tens of mA, then TPS56623x will work in light-load operation. Do you care the efficiency that time? If not, you can use TPS566238.
