6.2 Input Capacitor

PVIN provides power to the MOSFETs for the switch mode regulator section and the gate drivers. Due to the high switching speeds, a 10 μF capacitor is recommended close to PVIN and the power ground (PGND) pin for bypassing.

Analog V_IN (AVIN) provides power to the analog supply circuitry. Careful layout should be considered to ensure high-frequency switching noise caused by PVIN is reduced before reaching AVIN. A 1 μF capacitor as close to AVIN as possible is recommended.
