DC DC converters serve a wide range of applications, from powering communications equipment and military electronics to battery charging and motor control. The AVD85-48S05TL DC DC converter is a specific type of converter used in many applications. This article will discuss the functionality and application field of this converter, as well as its working principles.

Functionality:

The primary function of the AVD85-48S05TL DC DC converter is to convert direct current (DC) power from one voltage to another via the use of an integrated electronic circuit. It is designed to accept an input voltage of 6 to 36 VDC and output a precise 5VDC at 8.5A with a very low ripple. This converter has a high efficiency (typically 75 to 85%) and operates in temperatures up to 70ºC without needing a heatsink. It is also RoHS compliant. This converter is available in two variations: Surface Mount (SMT) and Through Hole (THT) mount, making it suitable for both types of engineering applications.

Application Field:

The AVD85-48S05TL DC DC converter is widely used in a variety of applications, particularly in industrial, automotive, and military applications. Its low ripple output voltage makes it suitable for use in precision circuits and process control systems, while its high efficiency and high temperature tolerance make it an ideal choice for vehicular applications. It is also used in power monitoring systems for video and data transmission, radar systems in military applications, and cabin electronics for aviation applications. The ability to operate in harsh environments ensures reliable and safe operation, even in extreme temperatures.

Working Principle:

The AVD85-48S05TL DC DC converter utilizes a switching circuit technology that consists of two distinct circuits: one for converting the input voltage to a high voltage while a second for converting the high voltage to the required output voltage. This technique works by using high frequency alternating switching currents and voltages that are applied to the circuit. A current transformer and voltage transformer then convert this alternating current into a direct current of the required voltage and current, thereby providing a regulated output voltage.

The AVD85-48S05TL DC DC converter uses MOSFET switches to regulate the current through the circuit, providing a clean, ripple-free output with high efficiency. The use of synchronous rectification and a clever circuit design also help to maximize efficiency, resulting in significantly lower energy losses than other types of converters. In addition, the device features an automatic input voltage protection system to protect against short circuits and voltage surges, ensuring long-term reliability.

In summary, the AVD85-48S05TL DC DC converter is a reliable and efficient power conversion solution for many applications. Its high voltage and current ratings, as well as its low ripple output voltage, make it suitable for precision electronics and process control systems, while its high temperature tolerance makes it an ideal solution for automotive and military applications. Furthermore, its synchronous rectification and clever circuit design greatly improve efficiency for an overall cost-effective solution.
