    Tips: What is the difference between a switching power supply and a linear power supply?

    What is a linear power supply?
    Linear power supplies are designed for low noise and are generally considered quiet because there is no high frequency switching. They can be used wherever excellent regulation and/or low ripple is required, as well as low electromagnetic emissions and excellent transient response. Linear power supplies can only step down the input voltage to produce a lower output voltage. Linear power supplies typically use large transformers to step down the voltage from the AC line to a much lower AC voltage, and then use a series of rectification circuits and filtering processes to produce a very clean DC voltage. The downside is weight, size, and inefficiency.

    What is a switching power supply?
    Switching power supplies are designed for high efficiency and small size. They contain a switching regulator to efficiently convert electrical energy. Switching DC power supplies regulate the output voltage through a process called pulse width modulation (PWM). The PWM process generates some high-frequency noise, but enables switching power supplies with very high power efficiency and small size. With good design, switching power supplies can have excellent load and line regulation. They can step up or step down the input voltage to obtain the desired output voltage. Switching power supplies are more efficient than linear regulators because switching transistors dissipate very little power when used as switches. However, this switching creates noise, which can be reduced by filtering.

    In today's electronics, switching power supplies are often preferred due to cost, size and efficiency. The decision to use a linear or switching power supply depends on the application and overall system requirements.
