Many of the problems that occur when transforming a design from the mythical world of textbooks and SPICE to the real world emanate from the non-ideal power supply. Real power supplies can cause noise ...
Figure 1 shows a switching regulator that can generate a lower voltage from a high voltage. In this type of circuit, the bypass capacitor (CBYP) is especially important. It has to support the switched ...
All isolated DC-DC power converters include an input filter, output filter, transformer, primary-side switch(s), secondary-side rectification and a controller. The controller can be referenced to ...
Separating the power/ground connections used for the analog sections from those used for the digital areas will improve the isolation of the power supplies. Adding external/internal filtering should ...
