TPS51200: about cover the two DDR4 controller

Part Number:TPS51200

Hi,

Customers use TPS51200 in DDR4 circuits.
Currently, one TPS51200 is used for one memory controller.

However, customers find that the current is small,
Customer is trying to use one TPS51200 for two memory controllers.
Do you have any problems with this?

Best Regards,
Yusuke
