Layout Guideline
Careful circuit board layout is critical to achieving low switching power losses and clean, stable operation. The EV kit also
serves as a Maxim recommended layout of the MAX77857. If POK or fault interrupt functionality is desired, then high-
density interconnect (HDI) PCB is required to route to the POKB/INTB pin. Otherwise, HDI PCB is recommended but not
required.
Figure

Figure 17
show examples of non-HDI and HDI PCB layouts for the MAX77857 WLP
package. Use the provided layout files for guidance when designing with the IC. The IC data sheet contains a list of useful
tips and guidelines for achieving the best possible layout. They are repeated here for convenience:
