The power supplies in complex systems are divided into multiple power domains to provide noise isolation as well as to improve power efficiency with options to turn on/off different power islands.

Voltage regulator efficiency is expressed as a percentage of the ratio of the output voltage to the input voltage. Although many voltage regulators supply a single outlet for conditioned power, some ...

The Art of Electronics, on regulators. Chapter 5 probably made most of an impression on the late-teenage me, because it explains voltage regulation and power supplies both linear and switching.

Linear voltage regulators are key components in any power-management system that requires a stable and ripple-free power supply. A subset of linear voltage regulators is a class of circuits known as ...

They generate the output power by converting an input signal into an output signal. Switching power supplies make use of a switching element or regulator (normally a power transistor) in order to ...

Figure 2 Bootstrapping the IC switch voltage to the input in the circuit of Figure 1 improves efficiency by about 3%. Of course, the FET actively turns on when the source goes low. But simply using ...
