Other power supply modules in embedded are power modules or components that are used for powering an embedded system and providing additional sources of power. They typically include DC/DC converters, SuperCapacitors, battery backup modules, and power management ICs. The modules that are used in embedded applications must be able to handle a wide range of voltages and power levels. DC/DC converters, for example, can provide a wide range of voltage levels, from 0.8V to 60V, and are very efficient and reliable in providing power to systems. SuperCapacitors, which are rapidly becoming popular, allow systems to store energy more reliably and efficiently than traditional batteries. Battery backup modules provide a source of power in the event of a power failure, while providing protection against current spikes or fluctuations. Finally, power management ICs enable an embedded system to be able to use the most power efficient source of power available, while optimizing the way energy is used within the system.
