Part Number: TRF3722

Hi team,

Could you help to provide TRF3722's current consumption on each power pin?

My customer is asking it for board/power design.

Thank you!

Hello Luke,

According to the data sheet the 3.3V rail consumes approximately 374 mA (or 328 mA when the LO out is off). If supplying 5V for the VCC_TK, the 5V rail would consume 21mA. See figure below.

Or is your question for the current consumption on each individual pin itself? (Pins 4, 6, 35, 14, 16, 21, 23, 42, 32 ,33)

Regards,

-Oscar

Oscar,

Thanks for the reply.

But yes, I need the current consumption on each individual pin.

Do we have it?

Hi Luke,

Here is the average consumption for each individual rail along with the standard deviation. Units are in mA.
