When searching for the ideal energy source for any system you need to power, you have two main options: linear vs switching power supply.
So what’s the difference between a linear and switching power supply, and which is right for your unique needs? Each has its own unique advantages and disadvantages that are important to consider when choosing the best power supply.
But, this decision can get overwhelming - particularly for those who aren’t power supply savvy. Fortunately, we are - and we’re here to unpack everything you need to know. Here are the key takeaways on this switching power supply vs linear power supply comparison:
- Switching power supplies are more efficient and compact. This comes at the cost of more noise. You’ll find these in manufacturing, aviation, and other industries.
- Linear power supplies have a quicker response to fluctuations in load. They’re quieter, but less efficient and a bit larger. Common in communications, medical equipment, and laboratory devices.
- Output power scale influences cost. Linear is more economical at smaller outputs, whereas switching is less expensive at higher loads.
That being said there’s more that goes into choosing between a switching vs non switching power supply - accounting for noise, understanding circuit complexity, and other factors. We’re here to simplify everything for you.

What’s the Difference Between a Linear vs Switching Power Supply?
So what’s the difference between a switching power supply vs linear power supply?
When looking to power your devices, linear and switching are the two main types of power supplies available. Both work by converting AC or DC mains electricity into a low-voltage form that those gadgets can use; however, their efficiency, cost, size, and performance vary drastically.
What is a Linear Power Supply and How Does it Work?
Linear power supplies use a transformer to decrease the input voltage until it reaches the preferred level and then smooth out any extra energy by using a series-pass transistor that dissipates this excess in heat form.
Voltage regulation within these linear types of power is attained by modifying the resistance of the particular transistors, so as to keep an even voltage across itself at all times.
Linear power supplies offer benefits such as low output ripple and noise levels that make them the perfect choice for high-precision applications that require minimal sound.
Nevertheless, their efficiency is lower than switching power supplies since they dissipate surplus energy in the form of heat. This can lead to bulky and heavier units - an issue when space is limited.
What is a Switching Power Supply and How Does it Work?
Switching power supplies utilize a high-frequency switch circuit that modulates the input voltage on and off at an incredibly rapid rate in order to generate your desired level of output voltage.
And with this technology comes tremendous power supply efficiency gains - since they don't waste extra electricity by converting it into thermal energy like their linear counterparts do. Switching power supplies are truly revolutionary devices that can help cut manufacturing costs while providing superior performance.
Switching power supplies are ideal for applications where there is limited space because they are smaller and lighter than linear power supplies. Plus, their higher efficiency means that they’re more cost-effective in the long run.
On the other hand, switching power supplies tend to generate more noise and ripple in their output voltage than linear power supplies. This poses an issue for applications that necessitate high precision or low noise.
Moreover, these types of power supplies usually require additional components and can be relatively difficult to set up for beginners.
Linear vs Switching Power Supply: Which is Better?
So which is better linear or switching power supply? When it comes to recognizing the best power supply for your specific application, there is no one-size-fits-all solution.
Choosing between a switching power supply vs linear power supply can be tricky due to the advantages and disadvantages of each type of device - meaning that you must consider all factors before determining which option will yield optimal performance.
Pros and Cons of Linear Power Supplies
Pros:
- Low output ripple and noise, making them well-suited for applications that need high precision and low noise.
- A straightforward design with fewer components leads to more reliability and simpler repair.
- Lower price tag for lower power requirements.
Cons:
- May not be as efficient as switching power supplies, resulting in more heat generation and bigger size.
- Limited power output, making them unsuitable for higher power needs.
- Power supply voltage regulation may not be as precise, necessitating larger and pricier components.
Pros and Cons of Switching Power Supplies
Pros:
- Higher efficiency, resulting in less heat dissipation and smaller size.
- Higher power output, making them suitable as high-voltage power supplies for larger applications
- Lower cost for high-power applications.
Cons:
- Can introduce more noise and ripple into the output voltage than linear power supplies.
- Higher cost for low-power applications.
Key Applications for Linear and Switching PSUs
When it comes to high-power applications that call for both efficiency, compactness, and affordability, switching power supplies are typically the superior choice. Such applications range from computers to consumer electronics and telecommunications equipment.
Linear power supplies are the optimal choice for low-power needs where you want minimal noise, the utmost precision, and a convenient layout. These types of applications include audio systems, medical equipment measurements, and test instruments.
So, Which is Better: Switching vs Linear Power Supply?
So when comparing linear vs switching power supply, which is better?
Overall, switching power supplies are generally the better choice for most applications due to their higher efficiency, smaller size, and lower cost for high-power applications.
However, for low-power applications that require low noise and high precision, a linear power supply may be the better choice.
