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.
