  2. Supply Analog Devices ADP1071-1 ADP1074
    Galvanically isolated power supplies are used in numerous applications for different reasons. In some circuits, galvanic isolation is necessary due to safety considerations. In other circuits, functional isolation is used to block any interference ...

  1. EDN As much as we’d prefer to be able to use just unforced, natural convection cooling, many designs and installations simply cannot be cooled adequately by the low level and uncertainty of airflow that this low-cost, reliable approach ...

  2. By Michael O'Loughlin EDN In certain applications, design requirements may call upon a system's switched-mode power supply to more promptly deliver its output than would the garden-variety power supply. Figure 1 shows such a supply's ...

  8. Supply Analog Devices ADP2370 ADP2441
    Switching regulators use a duty cycle to realize voltage or current feedback control. The duty cycle is the ratio of the turn-on time (T ON ) to the complete cycle length, the turn-off time (T OFF ) plus on time, and defines a simple relationship ...
