Power ModulesPower modules are electronic devices that are designed to provide a stable and regulated power supply to other circuits. They typically consist of a DC-DC converter, which can step up or step down an input voltage to a different output voltage, as well as other components such as inductors, capacitors, and power transistors. Power modules are commonly used in a wide variety of applications, including power supplies for electronic devices, battery chargers, and portable electronic devices. They can be used to convert a voltage from one level to another, as well as to provide isolation, filtering, and protection to the power supply circuit.
