[Information] The Secret of Low Noise

[Information] The Secret of Low Noise

Introducing a design that does not produce the "noise," which is the fate of switching power supplies.

In this document, we introduce how the power supplies handled by Daitron achieve low noise. Generally, switching power supplies generate noise due to the ON/OFF switching. Daitron has made improvements to this switching method. We will reveal the secret of a "power supply that does not produce noise" rather than just a "power supply that suppresses noise."
