Working Principle

The XMS50091 integrated AC DC conversion module consists of three primary components: an AC-DC rectifier, a DC-DC converter, and an AC-DC voltage regulator. The rectifier converts a voltage source from alternating current (AC) to direct current (DC). It is composed of six out-of-phase full-bridge circuits and over-current protection circuits. The DC-DC converter steps up or steps down the DC output voltage in order to match the application requirements. The AC-DC voltage regulator maintains the output voltage power supply stability within a certain range. It is composed of a pulse width modulation (PWM) control circuit, an AC signal sample circuit, a current detection circuit, and a voltage detection circuit. All the components work together to ensure that the output voltage remains stable, and that the equipment runs safely while consuming low energy.

Conclusion

The XMS50091 integrated AC DC conversion module is a highly reliable and efficient solution for powering a wide range of DC-based equipment in a power-constrained space. With its integrated rectifier, DC-DC converter, and AC-DC voltage regulator, the module offers a one-stop solution for multiple power applications. Moreover, its ability to provide hot-pluggable power management makes it an excellent choice for applications dealing with multiple DC-input voltages. With such features, the XMS50091 integrated AC DC conversion module is ideal for powering small projectors and notebook computers.
