Hello , I am trying to the EVM setup using a concentric cylindrical primary and secondary coil (secondary inside). At power up I manage to get the beep and the status green light blinking but I am not able to see 5 V at the out pin of the BQ51013 evm. Can anyone please give any insights? on a cro (ACin pins i get around 5Vp-p voltage ).

Actually I guess now I am getting blinking red on the status pin D5. Is it because of PMOD?

Hi,

Please make sure that the coils aligned and the communication between the Tx and Rx is good (Modulation depth). Does Vrect go up? Are you able to get 5V at all, or never start up? Make sure the tuning of the coil is correct

Thanks

Tahar
