• DC DC Converters: RAZ-1205S-R Application Field and Working Principle

• Overview

A DC-DC converter is an electronic device used to convert one form of DC power to another. The RAZ-1205S-R is a high performance DC-DC converter developed by Exceedex Technologies, designed for applications in the telecommunications and automotive industries. It features a robust design, including current limiting, short-circuit protection, voltage and temperature compensation, and a wide range of output voltages, making it ideal for both industrial and automotive applications.

• Application Field

The RAZ-1205S-R DC-DC converter is widely used in telecommunications, automotive, and other industrial applications. In telecommunications, it can be used to power base station amplifiers, transceivers, and other equipment that require a reliable source of DC power. In automotive applications, the RAZ-1205S-R provides a reliable alternative to alternators and batteries, while its wide range of output voltages makes it suitable for powering engine and transmission controls, air-conditioning systems, navigation systems, lighting, and other electrically powered systems. In addition, the RAZ-1205S-R has been used in industrial applications, such as powering control systems, factory automation, and industrial machinery.

• Design & Working Principle

The RAZ-1205S-R DC-DC converter is based on a step-down switch-mode topology with synchronous rectification. It features a wide input voltage range of 8 V to 40 V, and its output voltage is adjustable from 5 V to 12 V. The unit is protected by short-circuit, overload, and over-temperature protection circuits, which protect the device from damage due to excessive current, short-circuits, or high temperatures. The converter also features voltage and temperature compensation, which helps maintain consistent output voltages even under changing loads or environmental conditions.

The RAZ-1205S-R utilizes a patented switching technique that incorporates active peak current limiting and active current sharing. This technique allows the converter to transition from its normal operation to the overload current limit without a noticeable drop in the output voltage. This eliminates the need for a bulky transformer, reducing its overall size and power loss. It also eliminates the need for snubber circuits, improving its efficiency.

The RAZ-1205S-R DC-DC converter is an efficient and reliable power solution for a wide range of applications. Its robust design, wide input voltage range, and adjustable output voltage make it ideal for use in telecommunications, automotive, and industrial applications.
