DC-DC converters have advanced over the years to provide efficient, economical, high performance alternative solutions for applications that involve powering assemblies from a variety of battery, DC, or AC sources. The ISL8272MAIRZ-T is a step-down DC-DC converter specifically designed for these types of applications. This article provides an overview of its application field and working principle.

Application Field

The ISL8272MAIRZ-T is a dual-output, integrated step-down DC-DC converter that provides a stable and reliable operation in a wide range of applications. Some of the most common applications for this converter include automotive, industrial, and consumer electronic products. It is most commonly used in automotive infotainment systems, car navigation systems, and power tool applications where two outputs are needed from one power supply.

This converter is also frequently used for up-conversion from a 12V source to a 3.3V or 5V output, making it an ideal solution for powering modern technologies and embedded microcontrollers in automotive, industrial, and consumer products. The converter is capable of handling a wide input voltage range of 4.5V to 16V, which makes it suitable for most automotive, industrial, and consumer electronic applications.

The ISL8272MAIRZ-T is also a cost effective solution for powering remote radio frequency (RF) transceivers due to its high efficiency of 98.7% at 5V output power. The integrated over-temperature protection ensures that the power supply is safe even in extreme temperature environments.

Working Principle

The ISL8272MAIRZ-T DC-DC converter utilizes a switched-mode topology that enables power conversion with high efficiency and low noise. This type of converter is designed to step-down the input voltage into a lower voltage, without any significant reduction in the output current. The output power is converted into a voltage level suitable for the particular application at hand.

The ISL8272MAIRZ-T DC-DC converter is composed of two main components: a regulating inductor and a power switch. The regulating inductor regulates the output current by taking energy from the input voltage source and storing it. Then, the current is released through the power switch to turn the output voltage into a lower voltage level. The output power is then adjusted and regulated with the help of a voltage control circuit to match the requirements of the particular application at hand.

The ISL8272MAIRZ-T DC-DC converter has a current mode control topology, which enables it to respond quickly to changes in the output current. It also includes built-in protections such as over-voltage, under-voltage, and over-temperature protection, which ensures that the converter will not be damaged due to harsh operating conditions.

Conclusion

The ISL8272MAIRZ-T is a highly efficient and reliable step-down DC-DC converter designed for a wide range of applications. It is capable of handling a wide input voltage range, making it suitable for most automotive, industrial, and consumer electronic applications. The converter also has a high efficiency of 98.7% at 5V output power, making it an ideal solution for powering remote RF transceivers. Finally, it includes built-in protections such as over-voltage, under-voltage, and over-temperature protection, as well as current mode control, which ensures reliable operation in a variety of conditions.
