The output current of the output must pass through the power transistor due to the linear design. This thermal stress demands that the lines power supply use a heat sink to eliminate energy loss. This can be seen as a drawback of how linear mode power supply occurs in its system. The final shock of the linear regulator is that if there is a large difference between the input and output voltage it is not as efficient as the switch-mode power supply. It is important to consider many different factors such as dropout voltage and load voltage, while linear mode for your application should be at the efficiency level of the power supply.
- The open frame SMPS allows your device to operate a separate voltage power source, it can be easily replaced, acting like a battery charger, will extend the life of the device.
- As an adapter, a 12V battery charger as well as any other voltage produces less heat, so less energy is required. Once the battery is fully charged, the device can run without much power requirement.
- Using an external power adapter eliminates any surrounding problems to meet safety requirements. For travel, the power supply incorporates many jurisdictional standards and allows a personal computer to be carried at all times.
- With a rechargeable battery and power supply, the device can be lighter and requires fewer electrical components.
