DC DC Converters

DC-DC converters offer a wide range of advantages for electronic applications. They provide clean, efficient power transfer, excellent performance, and can be tailored easily to specific power requirements. In this article, we will explore the application field and working principle of the HQA2W120W150V-007-S DC-DC converter.

Application Field

The HQA2W120W150V-007-S is a high efficiency, regulated DC-DC converter. It has been designed to offer a very high load and line regulation performance when used with high voltage switching supplies. The converter is ideal for applications such as automotive electronics, industrial automation, and telecommunications. Specifically, it can be used as an input for microcontroller systems, battery chargers, and regulated power supplies.

Working Principle

The HQA2W120W150V-007-S is based on a flyback converter topology. This topology consists of a primary switching circuit and a secondary rectifying circuit. The primary switching circuit is built around the main switching transistor (MOSFET/IGBT). This semiconductor switch opens and closes during normal operation, at a frequency determined by the control circuit. This causes energy to be stored in the transformer\'s magnetic field, and voltage to be induced on the secondary side. The secondary side rectifying circuit then rectifies this voltage and filters the output. The output voltage is regulated by adjusting the duty cycle of the switching transistor.

This DC-DC converter has an adjustable output voltage range of 20V to 150V, and can deliver continuous currents up to 120W. It also has high efficiency of up to 93%, and a wide operating temperature range of -40°C to 85°C. Additionally, it has high protection features, including short circuit and over voltage protection.

Conclusion

The HQA2W120W150V-007-S DC-DC converter is a high efficiency, low cost solution for automotive, industrial, and telecommunications applications. It has an adjustable output voltage range of 20V to 150V, and can deliver continuous currents up to 120W. Additionally, it has high protection features, and an operating temperature range of -40°C to 85°C. So if you need an efficient and reliable DC-DC converter for your application, then the HQA2W120W150V-007-S could be the perfect solution.
