AM5749: Connect to TPS6590379 with other devices

Daisuke Maeda

Part Number: AM5749

Our customer wants to know how to connect AM574x to TPS6590379 with other devices.

In the power connection user's guide (SLIU011F), the outputs of TPS6590379 connected to other devices (peripherals) are listed below.

 - LDO2 (1.8V)
 - SMPS3 (DDR)
 - SMPS9 (3.3V).

Is it NOT recommended that 1.8V outputs (listed below) of TPS6590379 be connected to other devices?

 - LDOLN
 - LDO3
 - LDO4
 - LDOVRTC

Since each of LDOLN, LDO3 and LDO4 is connected to the power input of AM574x PLL or PHY, I suppose each of the outputs should not be connected to other devices to avoid the affects of noise even if the rated output current is not exceeded.

Best regards,

Daisuke

    Hi,

    Our customer will follow the user's guide (SLIU011F) to connect 3.3V IO (VDDSHVx) with other devices to an external power supply instead of SMPS9 and to connect each of other AM57x power supply inputs without other devices to each of TPS6590379 outputs.

    Please close this thread.

    Best regards,

    Daisuke
