Power Module Stable Power Supply for Communication Equipment

A buck - boost converter module is a type of power converter module which can step - down (buck) as well as step - up (boost) the input voltage. This makes it useful in a wide range of functions. In communication devices, it can be used to stabilize the voltage which can vary during charging and discharging of the battery. For instance, if a communication device's battery voltage ranges from 3.7V to 4.2V, a buck - boost converter module can regulate it to a constant 3.3V. It works by releasing energy stored in an inductor or capacitor at a different voltage level.
