10.2 Layout Example
Figure 20. Layout Example of VDCDC1 The most important layout practice is the placement of the input capacitor. The input capacitor should be placed as close as possible to the VINDCDCx and GND pins of the converters inorder to minimize the parasitic inductance and loop.
The second most important layout practice is to minimize the feedback cross-sectional loop of the converters. Route the feedback trace along a close path of the VOUT and switch nodes.
