10 Layout

Proper layout is important in any regulator design. The TPS92410 is a linear regulator which simplifies layout compared to a switching regulator, however some consideration should be taken.

10.1 Layout Guidelines

Components between CPS, CDD, DOV, COMP, VREF, MULT, and VCC to ground (GND) should be placed directly next to the device as shown in Figure 18. The linear MOSFET as well as the GDL and CS traces should be placed as close the TPS92410 as possible as well.
