APPLICATIONS INFORMATION
PCB LAYOUT
For optimum voltage regulation, the loads should be placed as
close as possible to the source of the output MOSFETs and
feedback to the sense inputs should be taken from a point as
close to the loads as possible. The PCB tracks from the loads
back to the sense inputs should be separate from the output
tracks and not carry any load current.
Similarly, the ground connection to the ADM1052 should be
made as close as possible to the ground of the loads, and the
ground track from the loads to the ADM1052 should not carry
load current. Correct and incorrect layout practice is illustrated
in Figure 3.
