TMS320C6652: Recommended VID power IC LM10011

Expert 3225 points
Part Number: TMS320C6652
Other Parts Discussed in Thread: LM10011, LM10010, TIDEP0011

Hi Team,

As recommended by TI, we are currently planning to mount the LM10011 as a C6652 core voltage control IC, but when replacing the LM10010
What kind of impact do you think? I understand that you recommend the LM10011, but when using both devices
I want to check the differences.
Also, what kind of thinking should you choose about the resistance value to be connected to the SET terminal of the LM10011 and tell what effect it has as a result?

Thanks

Best regards,

Shidara

    Hi,

    The recommendations for setting VID & VCNTL in the case when LM10011 IC is used are described in Section 2.2.1.4 LM10011 and Analog Controller Solutions in the Hardware Design for Keystone I Devices: www.ti.com/.../sprabi2d.pdf

    There are also user guides available through the link in Section 2.2.1.3 Supported Power Supply Solutions in the same Hardware Design for Keystone I Devices.

    Best Regards,
    Yordan

    Hi Yordan-san

    Thanks for your reply. let me change my question.

    Would you advise if we use LM10010 instead of LM10011, is it no problem?

    Because my customer would like to use LM10010 since it seems almost compatible IC.

    Thanks

    Best regards,

    Shidara

    Shidara,

    You want to use the LM10011.  It is basically a replacement for the LM10010 as it has additional precision needed for VID operation.  The LM10011 is a drop-in replacement requiring no change to the board to be used.

    The attached spreadsheet allows for various resistor solutions to be calculated.  Be sure that the resulting voltages align with the VID table in the KeyStone I Hardware Design Guide.

    Please refer to TI Design TIDEP0011 (PMP8275) for a use example and additional reference.
