Power factor correction (PFC) is an important component of secure power supplies in the electrical and electronic industries. Without a reliable PFC solution, the risk of damaging delicate electronic components increases. As suppliers strive to meet the power requirements of ever more demanding applications, the need for efficient, reliable PFC solutions is greater than ever.

The MP44011HS-LF-Z is a highly efficient, advanced single-stage, flyback PFC controller that is designed to meet the highest standards in both quality and performance. With its innovative design, the MP44011HS-LF-Z is able to achieve ultra-low input and output ripple, ensuring power supplies that are safe for the environment, reduce electromagnetic interference (EMI), and are compatible with the toughest standards in safety, reliability, and return on investment.

Application Field

The MP44011HS-LF-Z is suitable for almost any application that requires a highly efficient, noise free power supply. Due to its advanced design, the unit can convert any DC voltage from 1.5 to 48V with a single-stage, flyback, no-electrical-load buck or boost PFC solution. As such, it is perfectly suited to a variety of applications, including personal computers and servers, home audio-video applications, automotive systems, remote and distributed systems, mobile devices, and industrial equipment.

Working Principle

The MP44011HS-LF-Z adopts a two-stage working principle, consisting of a power factor correction(PFC) stage, followed by an isolated buck or boost stage. During the PFC stage, the unit actively adjusts the current output and monitors the current waveform of the power network. The output current is processed to follow a sinusoidal shape, bringing the input power factor of the power supply up to 0.9 or greater. This phase is identified by the Power Factor Corrector (PFC) indicator on the PCB.

In the isolated buck or boost stage, the unit actively adjusts the output voltage and monitors the voltage waveform generated by the power network. The output voltage is processed to follow a sinusoidal shape, providing a highly efficient source of clean and noise-free power. This phase is identified by the Voltage and Frequency Response indicator on the PCB.

In addition to its two-stage working principle, the MP44011HS-LF-Z is equipped with a range of advanced features, including soft start, low RDSON power MOSFET for improved power dissipation, and adaptive-mode operation for improved efficiency. Combined, these features ensure the MP44011HS-LF-Z delivers reliable, safe and long-lasting power supplies for any application.

Conclusion

The MP44011HS-LF-Z is a highly efficient, advanced single-stage, flyback PFC controller that can meet the highest standards in both quality and performance. The innovative design of the unit allows it to achieve ultra-low input and output ripple, suitable for any application that requires a noise-free power supply, including personal computers and servers, home audio-video applications, automotive systems, remote and distributed systems, mobile devices, and industrial equipment.
