SK-AM62: SD card circuit design consultation

Rain Wang

Part Number: SK-AM62

Hi TI

The power supply of the SK-AM62 development board VDDSHV5 is designed with dual LDO.

I think this power supply is for the power of the relevant IO port of the SD card. If the customer does not use the SD card, will this power supply be needed?

This dual-output LDO is only implemented in SK-AM62 for SD Card support. You should connect the respective VDDSHV IO supply to a fixed 1.8V or 3.3V power source if your design is not using an SD Card.
