Hi,

For 2x, 3x 4x, Stackable with current share:

Can it be set via pin strap? If it can, pls send me the pin strap setting/document.
All the pin strap setting will be overwritten by PMBus command setting, right?

Thanks,

Tim

Hello Timothy,

Only the loop controller device (master) needs a resistor divider at the ADRSEL pin. then use (ECh) MFR_SPECIFIC_28 (STACK_CONFIG) to configure the device.

Thanks

Hi Tahar,

Can I use pins-trap only to set 2x or 3x devices for current share? do you have any documents for this?

Thanks, Tim

Hi Timothy,

Is there a reason you want to use TPS546D24 instead of TPS546D24A? Because TPS546D24A is a newer version and we generally recommend it for new designs.

In either devices, you can set it to 2x or 3x stackable with pin-strap only and no PMBus programming required.

This is all documented in the datasheet.

Yes, we offer Evaluation boards for 2x stackable for both devices.
