MPM81

DC-DC converters have become an indispensable part of the modern power supply systems and their applications have grown significantly in recent years. As one of the most popular DC-DC converters, the MPM81 is becoming increasingly popular in various industries and applications. This article will provide an overview of the MPM81 application fields and working principle.

The MPM81 is designed for the lowest power level applications, such as from 5 watts to 75 watts. Its main application fields include personal electronics, consumer electronics, telecommunications and data processing, medical equipment, test and measurement systems, and automotive electronics.

The MPM81 has a wide range of input voltage (90V-132V, 180V-264V/ 127V-423V/ 253V-528V), as well as a built-in auto-compensation technology to stabilize the output voltage. It also features many built-in safety features, such as over-voltage protection, short-circuit protection, and thermal protection, making it a reliable device for many applications. It is also highly efficient with a high nominal conversion efficiency of 94% that allows it to work with minimal power dissipation.

The working principle of the MPM81 is based on the flyback converter topology and uses pulse width modulation (PWM) control. The converter accepts the input AC voltage and converts it into a DC voltage, which is then stored in the primary inductor of the transformer. The output is generated by using PWM to switch the primary side MOSFET on and off. This pulsing of the MOSFET generates a magnetic field in the transformer core, which is then transformed to a proportional voltage output. The voltage is then regulated by the PWM control and the magnetic feedback of the transformer.

Overall, the MPM81 is an ideal solution for many low power applications due to its high efficiency, wide input voltage range, and numerous built-in safety features. Its working principle based on the flyback converter topology makes it a reliable and robust device that can be used in a variety of applications.
