The module power supply is a power supply that can be directly mounted on a printed circuit board, and is characterized by an application specific integrated circuit (ASIC), a digital signal processor (DSP), a microprocessor, a memory, and a field programmable gate array (FPGA). ) and other digital or analog loads provide power. In general, such modules are called point-of-load (POL) power supply systems or point-of-use power supply systems (PUPS). Due to the many advantages of the modular structure, the module power supply is widely used in switching equipment, access equipment, mobile communications, microwave communications, optical communications, routers and other communications fields and automotive electronics, aerospace and so on.  

 

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