11.3.1
VIN filter
A VIN pin low pass filter is suggested to reduce switching noise. The low pass filter is shown
in the next figure:
Figure 55.
VIN pin filter
Typical component value is: C = 1 µF.
11.3.2
PVCC and VCC
PVCC and VCC are connected with an internal resistor (about 10
Ω); this allows reducing
the external components. Connect the +5 V supply rail only to PVCC.
Use a bypass capacitor on PVCC pin. A VCC low pass filter helps to reject switching
commutations noise, this filter can be implemented simply adding a bypass capacitor on
VCC pin.
