The REC7.5-1209DRW/H2/A/M/SMD DC-DC converter is one example of a DC-DC regulator specifically designed for use in small, feature-rich applications. In this article, we will explore the application field and working principle of the REC7.5-1209DRW/H2/A/M/SMD.

Application Field

The REC7.5-1209DRW/H2/A/M/SMD is a 7.5V to 12V DC-DC converter featuring a maximum output power of 9W. It is an ultra-small module with a maximum dimension of 27.2mm x 16.3mm x 5.3mm and small profile height of just 0.9mm. As such, it is designed for space-constrained applications that require high performance and maximum efficiency.

Its applications range from consumer electronics, such as notebook computers, game consoles, and smart phones, to industrial automation and automation systems, such as connected and distributed system control panels and controllers for professional audio-visual systems. Thanks to its ability to accept input voltages from 5V to 18V and output a wide range of voltage levels, the REC7.5-1209DRW/H2/A/M/SMD can be used in a wide variety of products where space and efficiency are critical factors.

Working Principle

The REC7.5-1209DRW/H2/A/M/SMD is a synchronous, step-down DC-DC converter. It utilizes a synchronous rectification design, which enables higher efficiency than conventional linear regulators. It also features adjustable output voltages, under-voltage lockout (UVLO), thermal protection (OTP), and soft-start capabilities.

The converter utilizes two power switches: one high-side and one low-side switch. When these switches are activated, they rectify the input voltage, then pass it through an inductor. As the current passes through the inductor, it is resiliently stored in the form of energy, increasing its power. The energy is then discharged through the output voltage capacitor, significantly reducing the ripple voltage. Finally, the output voltage is regulated by a voltage control circuit. All of these elements work together to provide a reliable, efficient, and cost-effective solution for powering small, feature-rich systems.

Conclusion

The REC7.5-1209DRW/H2/A/M/SMD is a DC-DC converter designed for spaces constrained applications requiring high performance and maximum efficiency. It offers adjustable output voltages, under-voltage lockout, thermal protection, and soft-start capabilities. The converter utilizes a synchronous rectification design, which enables higher efficiency than a linear regulator, and two power switches for regulating the rectified input voltage through an inductor and output voltage capacitor. In conclusion, the REC7.5-1209DRW/H2/A/M/SMD is an effective and versatile solution for powering small-scale, feature-rich systems.
