What are the advantages and disadvantages of digital power module? What's the difference with the traditional power module?

Advantages of digital power module: when designing the module, the efficiency is higher, the calorific value of the power module is reduced, the product size is reduced while ensuring the stability of the motherboard, the occupied space is small, the physical value is stable, and the circuit control is more effective. Disadvantages: the production cost will definitely increase in the short term. At present, the motherboard using digital power technology is limited to the high-end products of various manufacturers.

There are some differences between digital power supply module and traditional power supply module: digital power supply does make some changes in raw materials, but the principle is the same as that of analog power supply circuit. It just integrates the original independent MOS tube and inductance coil. The original "towering" capacitors have all been replaced by better ceramic capacitors.
