The BP3 pin requires a minimum capacitance of 2.2 µF connected to AGND. The BP6 pin should have approximately 4.7 µF of capacitance connected to PGND. The PVIN pin should have approximately 1 µF of capacitance connected to PGND. To filter ripple on the AVIN pin, a small value resistor is recommended to be placed between PVIN pin and AVIN.
