Typical Application II (Double Data Rate I or II)
(Or tie REFIN pin to VMON1 pin)
(See notes below)
R*(VDDQ/0.6-1)
Note 2: Another way to set REFIN voltage is to connect VMON1 directly to REFIN pin.
Note 1: Set the upper resistor to be a little higher than R*(VDDQ/0.6 - 1) will set the final REFIN voltage (stead state voltage after soft-start) derived from
+3.3 TO +22V
the VDDQ to be a little higher than internal 0.6V reference. In this way, the VTT final voltage will use the internal 0.6V reference after soft-start.
