UN 0908a-P HEIR319306R0001 Advantages of the power module
There are many different Psus on the market from different suppliers, and each product has different input voltage, output power, function and topology. Psus are superior to integrated solutions because they save development time and allow products to be brought to market faster. The power module also has the following advantages:
● Each module can be rigorously tested separately to ensure its high reliability, including power-on testing in order to weed out substandard products. In contrast, integrated solutions are more difficult to test because the entire power supply system is closely linked to other functional systems on the circuit.
