Part Number: AM5749
Other Parts Discussed in Thread: AM5748

Hi team,

I’ve got questions on AM5749, I’d appreciate it if you could help me finding the answer.

During the powering up, could you share the current consumptions of below supply line?

・VDD_CORE

・VDD_MPU

・VDD_DSPEVE

・VDD_GPU

・VDD_DDR

Is there any other line need more than 0.5A of current during the powering up?

Best regards,

Kurumi,

The peak current consumption of the SoC is guaranteed to be below the PMIC/Buck/LDO capacity that is implemented on the AM5748/AM5749 EVM. We recommend that you follow that implementation, or provide a topology that meets or exceeds that implementation.

Kyle

Hi Kyle,

Yes, I understand the current consumption would be below the power management IC’s capacity.

The customer is using same power structure with AM574x EVM. Could you possibly tell the current consumptions of supply lines on EVM?
