Note:
1. The minimum voltage required in bypass mode is calculated using R_BYP from the DCDC specification table. Requirements for
other loads can be calculated as V_{DVDD_min}+I_LOAD * R_{BYP_max}.
2. AVDD and VREGVDD pins should be physically shorted.
3. VREGVDD must be tied to AVDD. Both VREGVDD and AVDD minimum voltages must be satisfied for the part to operate. .
4. The system designer should consult the characteristic specs of the capacitor used on DECOUPLE to ensure its capacitance val-
ue stays within the specified bounds across temperature and DC bias.
