DC-DC converters are widely used in a range of applications from automotive and medical to industrial and military. They provide a great deal of versatility and are suitable for both stationary and mobile applications. The AXA005A0X-SR is a DC-DC converter designed particularly for rugged systems, and is ideal for applications requiring wide voltage conversion ratio, high efficiency and reliability.

The AXA005A0X-SR is capable of delivering up to 250 watts of output power and a voltage conversion ratio of up to 25:1. It has a low input voltage range of 6 to 32 volts and an output voltage of 0.2 to 25 volts. The device is housed in and is capable of providing an operating temperature range of -25°C to +60°C (-13°F to +140°F).

The device is designed to provide high efficiency switching across the DC input range, allowing for extended operating life and improved reliability for the system. The switching frequency is adjustable between 30kHz and 300kHz, allowing the user to optimize the output for a specific application. The device also features an anti-ringing circuit which reduces transient noise generated by the switching process, leading to reduced EMI.

The AXA005A0X-SR is also designed to meet the needs of military and avionics markets for high reliability, high efficiency, low-noise and wide-input voltage conversion applications. The device features a built-in mechanism to safely shut down the output in case of an over temperature or over voltage event, ensuring system safety. The device also includes an EN55032 Class B compliant EMI filter to reduce electro-magnetic radiation.

In terms of working principles, DC DC converters such as the AXA005A0X-SR are designed to convert a direct current (DC) power supply into a different DC voltage or current. This is done by using an integrated circuit switching device, such as an insulated-gate bipolar transistor (IGBT). These transistors act as switches which are switched on and off at regular intervals, allowing for different power conversion ratios. This conversion process is known as Pulse Width Modulation (PWM).

In order to help regulate the output current and voltage, the device also includes a closed loop feedback system. This helps to ensure that the output voltage remains at the specified level, regardless of load changes. The regulation also helps to maintain a high level of efficiency by limiting the amount of heat generated through switching, as well as improving the accuracy of the power delivery.

The AXA005A0X-SR is a high-performance DC-DC converter that is designed for use in rugged applications, offering high efficiency and reliability. With its adjustable switching frequency and the ability to regulate output voltage, it is well-suited for a wide range of applications. The device is also compliant with EN55032 Class B, helping to ensure EMI compliance for military and avionics applications.
