The design of a switching power supply has always been considered a blend of magic and art by every engineer that designs one for the first time. Fortunately, today the market offers different tools ...

What are digital power supplies? The effects of EMI on switch-mode power supplies. Designing a filter to reduce EMI. How Silent Switcher technology changed the game in minimizing radiated emissions.

Power-supply designers frequently encounter projects where the input voltages are much higher compared to the low output voltages usually require to power the target equipment. Typical output needs ...

In Power Tip #3, we discussed how the source impedance of an input filter can turn resistive, and how it can interact with the negative input impedance of a switching regulator. At worst case, these ...
