DC-DC converters are devices used to convert a DC voltage from one value to another. The use of such components in modern electronic systems is growing, allowing for a range of advanced features and capabilities. The AEH10A48N is a component designed to address the specific needs of system designers who require a highly efficient, reliable and accurate DC-DC converter. In this article, we will explore the application field and working principle of the AEH10A48N.

Application Field

The AEH10A48N is a buck-boost DC-DC converter primarily used in automotive, industrial, and robotics applications. It can be used to convert a low voltage input from 9V to 18V, to a higher voltage output, for example, 36V. The converter has a wide temperature range of -40ºC to +95ºC, making it suitable for extreme temperatures, which is of great importance for automotive applications. It is designed to achieve efficiency levels as high as 95%, meaning minimal energy is wasted as heat. The AEH10A48N also provides an improved transient response over other buck-boost systems, so it reacts quickly to varying loading conditions.

Principle of Operation

The basic design of the AEH10A48N is a buck-boost converter. This type of topology is capable of delivering a higher output voltage than the input voltage or reducing the voltage depending on the operating mode it is set to. The AEH10A48N uses a high-frequency voltage transformer, operating at frequencies up to 1 MHz, to achieve the necessary voltage conversion with minimal noise.

The AEH10A48N contains two separate MOSFET switches, which are controlled by the internal control logic, to achieve the desired voltage conversion. The two MOSFET switches, operating in an alternating manner, deliver the pulses of voltage required for the transformer. The transformer then converts the voltage into the desired form while providing electrical isolation. The output voltage is then regulated through a feedback circuit that adjusts the duty cycle of the MOSFETs, thus maintaining the desired output voltage.

Conclusion

The AEH10A48N is a highly efficient and reliable buck-boost DC-DC converter, designed to meet the specific needs of automotive, industrial, and robotics applications. Its wide temperature range and improved transient response make it an ideal choice for these environments. Its working principle is based on two MOSFET switches operating in an alternating pattern to drive the high-frequency voltage transformer, and a feedback circuit to maintain the desired output voltage.
