With proper selection of the external MOSFETs, this device can support up to 50-A of load current in a two-phase configuration. As shown in Figure 18, to configure the TPS40322 for two-phase mode, FB2 is tied to BP6. In this mode, COMP1 must be connected to COMP2 to ensure current sharing between the two phases. For high- current applications, the remote sense amplifier is used to compensate for the parasitic offset to provide an accurate output voltage. The EN2/SS2 and ILIM2 pins are designed for multiple functions. They are used as VSNS and GSNS for remote sensing in two-phase mode. DIFFO, which is the output of the remote sensing amplifier, is connected to the resistor divider of the feedback network. Note that BP6 powers the remote sense amplifier. The DIFFO voltage must be 0.2-V lower than the BP6 voltage under all conditions. If BP6 is lower than DIFFO voltage, the converter loses regulation. To ensure no regulation loss, use a remote sense amplifier when the application output voltage is lower than 2.2 V. For an application in which the output voltage is higher than 2.2 V, the remote sense amplifier can be bypassed and the voltage output can be connected to the feedback resistor divider directly.
