PN5190 DPC

Hi.

I saw "PN5190 Dynamic Power Control Quick Calibration and TxShaping Demo", but If I don't have to use PN5190 for payaments, and I have to use it with small labels ISO15693 or different size of Mifare tags, I think that DPC is not the best solution, or what is the best way to setup the PN5190?

Hi PDS:

The Dynamic Power Control (DPC) is a feature that allows to control the transmitter current. Therefore the field strength depending on loading and detuning conditions. The DPC can be enabled and then dynamically adapts the output power.

DPC is a nice feature, it offers an improved RF performance. but it is not directly related to EMVCo.

Thank's Daniel for the answer.

The advantages of DPC are clear, but is not simple to configure. Which is the best procedure for setup the DPC if I don't have to "use EMVCO settings".

Hi:

You can refer to AN 12549, chapter 5: PN5190 and DPC
