As all other Volterra converter parts (VT1165SF, 57SF, 95SF), a single converter can be controlled by a resistor network, but when there's two or more in parallel they require a dedicated controller. Those VT243WFs are "in single channel mode" as they serve different loads (MVDDC, MVDDQ). Same config can be seen on HD4890 where there are two VT242WFs. HD4870 has only one VT1165MF, for GPU VDDC, yet there are two VT1165SFs that convert MVDDC and MVDDQ. Those VT1165SFs both have an external resistor networks to control them.
