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, low ESR capacitor, usually of around 4.7 μF. This

capacitor bypasses low frequency noises to the ground plane.
For high frequency transient noise, use a 0.1 μF capacitor as
close as possible to the VDD pin of the device. Placing the
decoupling capacitor as close as possible to the SSM2305 helps
maintain efficient performance.
