DC-DC converters are used to convert a DC input voltage to an adjustable DC output voltage or current. They are used to power electronics circuits that operate on variable supply voltages, as well as in power supply applications. The AXA01B18-L DC-DC converter is a switch-mode converter that uses a buck topology for achieving a high efficiency in applications where the input voltage can vary from 5V to 36V, and the output voltage is set to a fixed range between 0.9V to 28V.

The AXA01B18-L is a compact module optimized for few external components, making it an ideal choice for applications where space and cost are critical. It can deliver up to 10A of continuous output current and its small size also makes it suitable for use in portable devices. Its efficient design ensures a no-load power consumption of less than 0.3W at full load.

The basic structure of the AXA01B18-L comprises of an input stage, a switching stage and an output stage. The input stage contains an EMI filter as well as input terminals for powering the module. This stage also provides input over-voltage and over-current protection. The switch stage contains an inductor, FET switch, diode and a free-running oscillator, and it serves to convert a unregulated input voltage into a constant output voltage with the help of pulse-width modulation (PWM). The output stage consists of an output filter for providing a smoother output. It also includes an output voltage adjustment circuitry, and a current sense amplifier for measuring and controlling the output current.

The AXA01B18-L is designed to be highly efficient in a wide range of applications. It has a typical efficiency of over 95%, making it suitable for power-sensitive applications such as portable electronics. Additionally, it features a wide input voltage range, enabling stable operation over a wide range of input voltages. The module is also capable of providing an adjustable output voltage, making it ideal for applications requiring an adjustable output voltage.

In conclusion, the AXA01B18-L is an efficient and compact DC-DC converter designed to deliver an adjustable DC output voltage with high efficiency. Its small size and low power consumption make it suitable for use in applications where space and cost are critical, while its wide input voltage range and adjustable output voltage make it an ideal choice for a wide range of applications.
