The two are not universal

Modular power supplies are power supplies that can be mounted directly on a printed circuit board and feature power to application-specific integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memories, field-programmable gate arrays (FPGAs), and other digital or analog loads. In general, these modules are referred to as point-of-load (POL) power supply systems or point-of-use power supply systems (PUPS). Due to the advantages of the modular structure, the module power supply is widely used in AC equipment, access equipment, mobile communications, microwave communications, optical transmission, routers and other communication fields, automotive electronics, aerospace, etc.

Switching power supply is a kind of power supply that uses modern power electronics technology to control the time ratio of switch registration and shutdown to maintain a stable output voltage, and the switching power supply is generally composed of pulse width modulation (PWM) control IC and MOSFET. Switching power supply products are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instrumentation, medical equipment, semiconductor refrigeration and heating, etc.
