PROPER POWER SUPPLY DECOUPLING
To ensure high efficiency, low total harmonic distortion (THD),
and high PSRR, proper power supply decoupling is necessary.
Noise transients on the power supply lines are short-duration
voltage spikes. Although the actual switching frequency can
range from 10 kHz to 100 kHz, these spikes can contain frequency
components that extend into the hundreds of megahertz.

The power supply input needs to be decoupled with a good
quality low ESL and low ESR capacitor, usually around 4.7 μF.
This capacitor bypasses low frequency noises to the ground
plane. For high frequency transients noises, use a 0.1 μF
capacitor placed as close as possible to the VDD pin of the
device. Placing the decoupling capacitor as close as possible
to the SSM2301 helps maintain efficient performance.
