If the input voltage for the regulators is above 4 V, snubber components are needed at the switching nodes to decrease voltage spiking in the switching node and to improve EMI. The snubber capacitors C0, C1, C2, and C3 and the snubber resistors R0, R1, R2, and R3 are shown in Figure 31. The recommended components are shown in Table 13 and these component values give good performance on LP8752x-Q1 EVM. The optimal resistance and capacitance values finally depend on the PCB layout.
