The SA920N Power module is a power supply that can be mounted directly on a printed circuit board to provide power for application-specific integrated circuits (ASics), digital signal processors (DSPS), microprocessors, memory, field programmable gate arrays (FPgas), and other digital or analog loads. The power module is generally divided into AC to DC or DC to DC according to the conversion mode, and its integration is the highest. The main circuit of the switching power supply is integrated in the chip, which can realize the functions of broadband modulation isolation and a variety of protection.

SA920N power module is characterized by small size, high integration, high cost performance and the best performance indicators, only the simplest peripheral circuit, with a small number of discrete components can be used. When the product design needs to be changed, just parallel or replace the power module.

Because of the advantages of modular structure, power modules are widely used in switching equipment, access equipment, mobile communication, microwave communication, optical transmission, routers and other communication fields and automotive electronics, aerospace and other fields. Especially in recent years, due to the rapid development of data services and the continuous promotion of distributed power supply systems, the increase of power modules has exceeded the primary power supply.

The advantages of SA920N power module mainly include the following aspects:

Simple design: just select the appropriate power module, with a small number of discrete components can be used. The high integrated circuit inside the module makes the design more compact, and the supplier can also provide professional technical support and system solutions.

Save cost and time: The SA920N power module has a variety of input and output options, and can be repeated or cross-added to form a modular power supply, so as to achieve multiple input and output. Compared with separate, debugging is more simple and safe, which greatly simplifies the design and application and shortens the development time.

High reliability: Modules generally use automated processes to ensure quality and reliability. Discrete schemes are more difficult to conduct in-depth testing.

High power, density and efficiency: The module generally uses a multi-layer PCB back aluminum substrate, which has high power density and small volume, saving the space occupied by the system.

Easy maintenance, flexible design: In product applications, if there is a failure, just replace another module to work properly.

Wide range of applications: power modules can be widely used in aerospace, locomotive ships, military weapons, power generation and distribution, posts and telecommunications, metallurgy and mining, automatic control, household appliances, instrumentation and scientific research experiments and other social production and life in various fields.

In summary, the SA920N power module has the advantages of simple design, low cost, high reliability, high power, easy maintenance, and wide use.
