POWER SUPPLY DECOUPLING
To ensure high efficiency, low total harmonic distortion, and high
power supply rejection ratio, proper power supply decoupling
is necessary. Noise transients on the power supply lines are
short-duration voltage spikes. These spikes can contain frequency
components that extend into the hundreds of megahertz. Decouple
the power supply input with a good quality, low ESL, low ESR
bulk capacitor larger than 220 F. This capacitor bypasses low
frequency noises to the ground plane.
For high frequency transient noises, place two separate 1 F
capacitors as close as possible to the PVDD pins of the device.
Connect one of the 1 F capacitors between the left-side PVDD
terminals and PGND terminals, and connect the other 1 F
capacitor between the right-side PVDD terminals and PGND
terminals. Placing the decoupling capacitor as close as possible
to the SSM3302 helps to achieve the best performance.
