Power Supply PCB – The Ultimate FAQ Guide
Want to convert AC power into DC by installing a power supply PCB?
Are you planning to upgrade the efficiency of your home accessories, including your computer?
The following guide will help you!
We have compiled some frequently asked questions below based on our research.
Let’s get started.
What Is A Power Supply PCB?
Power supply PCB is precisely defined as the type of a power supply circuit that acts as a source of recharging all electronic systems and circuit boards.
The majority of the circuits having this kind of power supply are divided into sub-circuits. Thus, they are common in PCB power supplies.
If we talk further about this circuit power supply, they are considered the best converters in electrical circuits.
In electrical circuits, the power supply circuits lead to converting the input energy source into a steady output.
The output is always substantial to meet the power requirements of the load, system, or circuit.
The efficiency of the power supply PCB doesn’t depend on the efficiency of the source and the requirements of the load.
Besides the load requirements, the building of the PCB layout design is an integral part of power supply circuits.
Many versatile types of power circuits work in compliance with the power supply designs included in their development.
In addition to all these tasks, the power supply circuits are also famous for encompassing the actual power of the circuit systems ranging from PCs to home appliances.
In all devices, including computers, power supplies must convert AC into DC power with a reduction in the noise content.
Power Supply PCB
What Are The Applications Of Power Supply PCB?
Some important applications of power supply PCB are listed as under:
- It is used in almost all low power applications
- It is used in the linear regulators for the power control
- It is used in the switching regulators for integrating with the other circuits
- ICs are more than suitable for all mobile devices

Applications Of Power Supply PCB
What Is The Shelf Life Of Power Supply PCB?
The shelf life of the power supply PCB ranges up to 5 to 8 years.
However, the shelf life of the power supplies of PCBs depends on the quality of production and methods adopted to produce them.
The use of high-quality manufacturing parts, the availability of printed circuit boards, and the type of solder are used to make the power supplies impact their shelf life.
The shelf life of many other models of power supplies of PCB ranges up to many years in case of brand new items.
But the experts suggest it will change the power supplies of computers and other appliances after five years.
The primary reason behind changing the power supplies is the decline in efficiency and recurrent instability problems during working.
In addition to this, the old capacitors, frequent power surges, and mechanical stresses are also some other factors that can change the shelf life of the PCB power supplies.
Many premium manufacturing companies, including PCBMay, produce the highest quality of brand new PCB power supplies that come with extended shelf life.
So, you can reach them out to get your hands on the reliable and most efficient power supply circuit for your home appliance.
Shelf Life Of Power Supply PCB
What Are Different PCB Power Supply Design Options?
There are three main types of PCB power supply designs:
- The Liner Power Supply Circuit of PCB
This type of power supply is mainly used to convert the primary AC voltages to the lower DC voltage in all electronic appliances.
The most common conversion for the linear power supplies of PCB is 120V@60Hz to 24V DC.
Not only this but most of the power supplies of PCB are involved in the drive embedded products and many other industrial facilities.
- Switched Power Supply of PCB
Unlike the linear power supplies, the switched power supply circuits in PCB produce power on the highest quality of circuit boards.
With the help of switched power supplies, the switching regulator of the device uses SMPS to produce the higher grade current with extended efficiency.
The prominent production of current is also associated with the low heat while generating large heat-producing parts of devices.
- Battery-Based Power Supply of PCB
This power supply circuit is famous for its ability to work with constant voltage and current modes. In addition to this, you can use it with the low-noise linear types of regulators.
The battery-based power supply of PCB works in integration by tracking the pre-regulator to decrease the power dissipation in devices.
They are powered through ATMEGA328P and contain a programmed version of Arduino IDE.
Different PCB Power Supply Designs
What Are Best Practices For PCB Power Supply Design?
The best practices for PCB power supply design are listed as under:
This practice is related to the switched power supply designs of PCB. SMPS in this practice is designed to step down the voltage.
Stepping down the voltage coincides while stepping up the current in the circuits.
This SMPS design practice corresponds with stepping up the voltage while stepping the current in the electrical circuits.
Compared to the practices mentioned above, this SMPS design practice is related to the buck and boosts converters.
It corresponds with either stepping up or stepping down the voltage depending on the conditions in the working circuits.
However, regardless of the practices for power supply designs in PCBs, all boards must be cleanly designed with low noise production.
Thus, for making such a supply design of PCB that makes low noise while stepping up or stepping down the voltage, consider the following factors.
If the current supplies you’re working with have high levels, make sure to use the adequate trace widths of the circuits.
In addition to the adequate widths, consider the copper weight to tackle the high current levels in the circuits.
A power supply design of the PCB often gets hot while working. Thus, it is suggested to make a design that helps to dissipate the heat from the circuits.
The greater the heat dissipation, the greater will be the efficiency of the power supply design of the PCB.
For reducing the noise creating the power supply designs of the PCB, make sure to use compact and tight packages.
For making sure everything about the low noise production in the power supply designs of the PCB circuits is to adopt the best grounding strategies.
PCB Power Supply Design
What Is Thermal And Power Integrity In PCB Power Supply Design?
The thermal and power integrity in PCB power supply designs are described as under:
- Thermal Integrity in Power Supply Designs
Besides converting the power, the power supply designs are more related to thermal management since dissipating the heat during the conversion process is a key factor for better working.
For integrating the thermal factor of the power supply designs, you should build the regulator circuit with discrete components of the same size of the system.
While choosing the suitable regulator circuit, don’t forget to consider the thermal management options for all types of ICs in the power supply designs.
In addition to this, thermal integrity is also achieved by mounting a fan on the enclosure and providing substantial power with the help of AC signals.
But if you’re using the DC to DC power supplies, you’ll need a PWM signal. It helps to ensure cooling while running the components of power supplies in PCB circuits.
- Power Integrity in Power Supply Designs
Unlike the thermal integrity in the power supply designs, power integrity is also an essential feature. Different devices present on the circuit boards of PCB require different powers to run.
Make sure to use the power and ground planes in the circuit boards to promote the power integrity in the power supply designs of PCBs.
Besides this, managing the right power supply is more challenging than connecting an IC power source.
That is why experts suggest keeping a consistent voltage in the power supply circuits of the PCBs to introduce power integrity.
One of the potential problems that occur while ensuring the integrity of the power in PCB circuits is the availability of multiple supply voltages.
Moreover, the consistent power integrity will also require huge capacitors to provide a clean power supply in PCBs.
What Are Power Supply PCB Design Guidelines For Place And Route?
The power supply PCB design guidelines for place and route are listed as under:
- Layer Stackup
During the configuration of the multi-layer board, it is essential to have a ground or power plane in between the outer and inner power layers.
The power supply components and routing between the inner and outer layers must maintain sensor signals’ assurance.
Both planes of the inner and outer layers act as a shield for the sensitive signal traces coming from the outer layer’s noisy power components and routing.
- Component Placement of the Power Supply Design
Ensure to place the power supply parts close to each other to minimize the trace lengths and close the device loads.
While doing so, don’t forget to place the parts close to each for ensuring the shortness and direct delivery of the power through them. The inductor must be placed right after the output capacitor.
After placing the power components, make sure to place the remaining parts of the power supply close to each other.
- Trace Routing
The majority of the design route is right after the placement, but some power supply designs of PCBs route after completing the placement. Regardless of the way, make sure to place the complements with short traces.
Make sure to use the wide traces of current in the routing of the placements. Forty-five degrees or rounded corners are perfect in this case.
For reducing the chances of inductance, use the vias for power traces. This method will not cause any problem because the main power components are present on the same sides of the board.
Create a separate ground for all types of power components in the power supplies of PCB. In this case, the solid ground plane is mainly preferred.
Besides separating the power components, make sure to provide the optimal grounding of the power supply but don’t forget to isolate the noise of current return parts.
Connect the two planes to provide a tangible way to dissipate the heat from the power supply circuits.
You can contact PCBMay to get a brief insight into the detailed guidelines of power supply circuits for place and route.
