Tips: Linear Power Supply vs. Switching Power Supply

Efficiency

Linear power supplies are less efficient because they regulate voltage by dissipating excess energy as heat. This heat generation can lead to lower efficiency and requires larger heatsinks.
Switching power supplies are more efficient since they regulate voltage by rapidly switching the input voltage on and off. This switching mechanism minimizes heat generation, resulting in higher efficiency and smaller form factors.

Size and Weight

Linear power supplies tend to be larger and heavier due to the need for larger transformers and heatsinks to dissipate heat generated during voltage regulation.
Switching power supplies are typically smaller and lighter because they are more energy-efficient, generate less heat, and use compact components like inductors and capacitors, making them suitable for applications where space and weight constraints are important.
