DC to DC converters are an essential part of many electronics systems. They are used to convert a direct current (DC) voltage from one level to another, and are used in a variety of applications, from laptop chargers to solar panel grid-tie inverters. The REC3-1215DRW/H/B/M/SMD is an example of such a converter, and this article will cover the details of its application fields, features and working principle.

Application Field

The REC3-1215DRW/H/B/M/SMD is an industrial-grade, wide-input range, single and multiple output DC to DC converter. It is designed to operate from 9 to 36 VDC input with nominal 8.5 to 17 V and 18 to 36 V DC input capability, providing conversion efficiency of up to 90.5%. This type of converter is ideal for a variety of applications, including:

• Industrial grade high power conversion systems
• Mobile computer systems
• Wireless networks
• Communication systems
• AV applications
• Battery-powered devices

The standard package of the REC3-1215DRW/H/B/M/SMD comes in a SIP (Single In-Line Package) package, making it easy to install and provides excellent thermal performance due to its aluminum heat-sink design.

Features

The REC3-1215DRW/H/B/M/SMD boasts a range of impressive features, including:

• Current Mode Control for superior line/load regulation
• Unique design for low RFI/EMI emissions
• Fanless operation
• Over voltage protection & short circuit protection
• Output over-current and thermal protection

The REC3-1215DRW/H/B/M/SMD is also RoHS-compliant, ensuring that it meets all necessary environmental standards.

Working Principle

The REC3-1215DRW/H/B/M/SMD is a “buck type” DC to DC converter, meaning it can convert a higher voltage to a lower voltage. This is done by allowing current to flow between the input and output through a metal-oxide semiconductor field effect transistor (MOSFET), and then using that current to create a magnetic field. This magnetic field is then used to generate a voltage across the inductor, which is then finally output as a lower DC voltage.

The REC3-1215DRW/H/B/M/SMD utilizes a unique design, known as “Current Mode Control”, for superior line and load regulation. This allows the output voltage to remain less affected by changes in input voltage or current changes. This is achieved by comparing the output voltage and the reference voltage, then adjusting the duty cycle of the MOSFET in order to maintain the output voltage at the correct level. Additionally, the REC3-1215DRW/H/B/M/SMD’s unique design helps reduce RFI/EMI emissions, allowing it to meet international standards for such devices.

Conclusion

The REC3-1215DRW/H/B/M/SMD is an industrial-grade DC to DC converter, designed to offer superior conversion efficiency and reduce RFI/EMI emissions. Its wide-input range and multiple output capabilities make it an excellent choice for a variety of applications, including mobile computer systems, wireless networks, communication systems, AV applications and more. The REC3-1215DRW/H/B/M/SMD utilizes current mode control for superior line/load regulation, and is able to reduce RFI/EMI emissions due to its unique design. By understanding its application fields, features and working principle, one can make an informed decision when deciding which DC to DC converter is best suited for their system.
