DC-DC Converters are electronic circuits which convert one DC voltage to another. The AXH005A0XZ is a DC-DC Converter designed to convert a DC input voltage to a wide output voltage range. It is a highly efficient, four-pin device with a Mean-Time-Between-Failures of more than 720,000 hours. It can be used for applications ranging from telecoms to industrial applications.

The AXH005A0XZ comes with a wide input voltage range between 4.75V and 13.2V, making it suitable for a wide range of applications requiring different supply voltages. Its output voltage range is from 5V to 14V. The power capabilities are up to 200W with an efficiency up to 91%. The device has a maximum output current of 5A and is designed for operation in harsh environments from –40°C to +85°C.

The AXH005A0XZ is a highly reliable device. It comes with several built-in protection features. Overvoltage, overcurrent, over temperature, short circuit protection ensure that it can operate reliably in high-power and harsh environments. It also has an active current-limit protection function which prevents any overcurrent faults in the system.

The adjustable ON/OFF threshold voltage is another feature. This allows the user to tailor the operating frequency and duty cycle of the device to improve the efficiency or power delivery of their system. The device also has a soft start function which gradually increases the output voltage as the system is powered up, eliminating any inrush current.

The AXH005A0XZ works on the principle of a DC-DC buck converter with synchronous rectification. In the buck converter architecture, a MOSFET switch is connected in series with the load and the input voltage is applied across the switch. When the switch is active, the load is supplied with power from the input, and when the switch is off, the load is supplied with power from the output capacitor. The synchronous rectification is achieved by using two power MOSFETs on the output, one for active low side switch and one for high side switch. This reduces the conduction losses in the device and improves efficiency.

In conclusion, the AXH005A0XZ is an advanced DC-DC converter designed for a wide range of applications requiring different supply voltages. It features a wide input voltage range, high efficiency and reliability and several built-in protection features which make it ideal for high-power and harsh environments. Its adjustable ON/OFF threshold voltage and soft start functions make it easy to tailor the device to different applications and provide improved efficiencies. The device works on the principle of a buck converter with synchronous rectification.
