Due to its high efficiency, it is attractive for low-power applications, where it can cut down on energy wastage. It is also suitable for designs requiring low cost and reliable operation. The device is rated to provide up to 24W of output power, which makes it suitable for a wide range of applications. The ZL9024MAIRZ-T comes with integrated EMI/RFI noise filtering and a soft-start circuit, making it particularly suitable for sensitive applications.

Working Principle

The ZL9024MAIRZ-T is a buck-type DC-DC converter. It takes input DC power, passes it through an inductor and MOSFET switch, and reduces the voltage to a desired level before feeding it to the output. This reduction occurs at a much lower energy loss than if it were to simply be stepped-down through a resistor. The operating frequency of the device is typically adjustable in order to choose the optimal conversion speed. The higher the frequency, the faster the device is able to switch, resulting in higher efficiency.

At the start of operation, the MOSFET switch is open, allowing the inductor to build up magnetic flux. When the MOSFET closes, current begins to flow through the inductor and into the output. This current continues to build until the current limit is reached, at which point the switch is opened again. This process is repeated over and over until a steady output voltage is reached. The efficiency of the device is directly related to the amount of energy lost during the switching process.

Conclusion

The ZL9024MAIRZ-T DC-DC converter is a low cost, high efficiency and user-friendly device designed for DC power conversion in communications, medical, automotive and renewable energy applications. It has an attractive 95% peak efficiency, an adjustable switching frequency and integrated EMI/RFI noise filtering, making it particularly suitable for sensitive applications. Its buck-type operation ensures a low energy loss and high power conversion efficiency. It is definitely a great choice for a wide range of DC-DC power conversion applications.
