DC-DC converters have become increasingly popular due to their ability to provide a wide range of voltage and power levels from a source of low power. The AXB050X43-SRZ is a DC-DC converter designed to convert a wide range of DC input voltage into a regulated output voltage that is suitable for a variety of applications. In this article, we will discuss the application fields and working principle of AXB050X43-SRZ.

The AXB050X43-SRZ is a highly efficient non-isolated DC-DC converter which provides a wide input operating range from 4.5V to 48.0V, a fixed output voltage that can be set to either 25V, 26V or 28V,and a maximum output current of 50 amps. It is ideal for applications such as providing regulated power for industrial equipment, telecommunication systems, or for electric vehicles. The converter can also be used in applications where it is necessary to produce a variable voltage output with an adjustable current limit.

The working principle of the AXB050X43-SRZ is based on the ‘buck’ topology. In this topology, the converter uses a switching circuit to draw power from the input source and then regulate the output voltage. The switching circuit is comprised of MOSFET switches which are switched on/off in a methodical manner in order to draw power from the input and then regulate the output. The switching frequency of the converter is determined by the setting of the ‘frequency’ pin. The higher the frequency, the higher the efficiency of the converter as well as the higher the output power.

In order to maximize the efficiency of the converter the ‘discontinuous mode’ operation is enabled. This mode of operation allows the converter to stay in a low power consuming state when the load is low or in standby mode. This also helps to reduce the power losses as well as to extend the lifetime of the converter. The AXB050X43-SRZ can also be switched into a ‘synchronous mode’ when higher power output is required. The synchronous mode of operation allows the output voltage to the load to follow the same switching waveform as the input voltage, thus eliminating the power losses caused by rectifying the current.

The AXB050X43-SRZ is protected against over temperature, over current, and short circuit conditions. It is also equipped with adjustable soft start time and adjustable current limit. These features help prevent damage to the components of the converter as well as to the load during start up and when the load is suddenly removed or connected. The converter also features a power good signal which allows the system to detect when the output voltage of the converter is within safe limits.

In conclusion, the AXB050X43-SRZ is a highly versatile non-isolated DC-DC converter which is suitable for a wide range of applications. Its wide operating range of 4.5V to 48.0V and adjustable current limit makes it ideal for powering industrial equipment, telecommunication systems, or electric vehicles. Its high efficiency and ability to switch to synchronous mode when higher output power is required make it a great choice for applications requiring a regulated source of power.
