I'm planning on using the MMPF0100 as the PMIC for a Zynq Z7020-based design. AN4991 has a useful reference design for this application, I just have once concern regarding VTT, the DDR3 active termination rail. This rail needs to Source and Sink current during DDR3 activity, and I don't see this explicitly addressed in the datasheet. It mentions that SW4 has a VTT mode which tracks V_DDR3/2, but in this PWM mode does it also successfully sink the required current?
Many Thanks in advance,
