Hence to manage power and reduce power consumption has been a very important aspect of today’s system design ... in core power supply, and a smaller portion can be used to wake up the rest of the chip ...

But for circuits where weight, volume, or cost are a major concern, a transformer may be omitted in the circuit design in favor of some sort of transformerless power supply. While power supplies ...

This card enables engineers to design ... power rails with hardware-selectable or software-commanded range of voltages. The power rails are 3.3V, 5V, and 12V (main) and 3.3V and +/- 12V (auxiliary).
