SSM2380
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 is typi-
cally 325 kHz, these spikes can contain frequency components
that extend into the hundreds of megahertz.

The power supply inputs must be decoupled with a good
quality, low ESL, low ESR capacitor, usually of approximately
4.7 μF. This capacitor bypasses low frequency noises to the
ground plane.
For high frequency transient noises, use a 0.1 μF capacitor
as close as possible to the VDD pins of the device. Placing the
decoupling capacitors as close as possible to the SSM2380 helps
to maintain efficient performance.
