 What are the characteristics of the substrate power supply?

Miniaturization: The board power supply usually adopts digital control technology and high-frequency operation principles, which can convert the input voltage into a stable DC voltage output. This design allows the board power supply to have a smaller Size and lighter weight, while ensuring power conversion.

Characteristics of substrate power supplyIt can be summarized as follows:

MiniaturizationSubstrate power supplies typically use digital control technology and high-frequency operation principles to convert input voltage into stable DC voltage output. This design allows substrate power supplies to have a smaller size and lighter weight while ensuring power conversion.
High stability, high precisionThe working principle of substrate power supplies involves multiple processes such as transformer step-down, rectification and filtering circuits, high-frequency switching tube conversion, output circuit filtering, and voltage regulation, ensuring that the output DC voltage has high stability and high precision.
Good heat dissipation performanceSwitching power supplies with a metal substrate structure, such as aluminum substrate power supplies, have good heat dissipation effects. This is due to their metal substrate structure and very thin insulating heat dissipation layer, allowing the power supply to maintain a lower temperature during operation, improving the stability and reliability of the power supply.
High thermal conductivity and electrical performanceA 2-layer copper substrate power supply, as a realization method of substrate power supply, has high thermal conductivity and good electrical performance. This type of substrate power supply is suitable for various electronic devices that require high-density circuit design and complex power management.
Built-in integrationBuilt-in substrate power supplies integrate the power system onto the circuit board, eliminating the need for external power supply. This design enhances the portability of the power supply while reducing the risk of equipment failure due to external factors such as loose wires or disconnected plugs.
Wide range of applicationsSubstrate power supplies are widely used in electronic devices, communication equipment, computer equipment, medical devices, industrial control, and other fields. With the further development and application of electronic technology, the application of substrate power supplies will also expand to more fields.

In summary, substrate power supplies play an increasingly important role in modern electronic technology with their characteristics of miniaturization, high stability, high precision, good heat dissipation performance, high thermal conductivity and electrical performance, and built-in integration.
