Currently, various suppliers offer a wide range of power supply modules on the market, and different products vary in terms of input voltage, output power, functions, and topology. Using power modules can save development time and enable products to be brought to market more quickly; therefore, power modules are superior to integrated solutions. Power supply modules also have the following advantages: ● Each module can be individually and thoroughly tested to ensure its high reliability, including power-on testing to eliminate products that do not meet the specifications. In contrast, integrated solutions are more difficult to test, as the entire power supply system is closely connected to other functional systems in the circuit. ● Different suppliers can design modules of the same size in accordance with existing technical standards, providing engineers designing power supplies with a variety of options. ● The design and testing of each module are carried out in accordance with standard performance specifications, which helps to reduce the risks associated with adopting new technologies. ● With an integrated solution, if there is a problem with the power supply system, the entire motherboard must be replaced; whereas with a modular design, only the faulty module needs to be replaced, which helps to save costs and development time. Typical applications of DC/DC module power supplies include industrial instruments, digital circuits, electronic communication equipment, remote sensing and telemetry, as well as ground communication and scientific research equipment.
