2.4.4 IMON Output

As introduced in Section 2.2.4, IMON output signals with this reference design are inductor DCR current sensing signals. A pair of differential IMON output wires ISNS+ (TP22) and ISNS- (TP19) in schematic Figure 2-2 needs to be connected with the corresponding pins of IMVP multi-phase VR controller.
