DC DC Converters

DC-DC converters are electronic circuits that convert a direct current (DC) input voltage to a different DC output voltage. They are commonly used in power supplies, power conditioners, and other applications involving circuits that require the conversion of a given voltage source to be usable in a different circuit. The circuit topology used to achieve this power conversion is named after the type of power converter used in the circuit, for example, a step-down converter, a two-terminal or flyback converter.The IEH48025A120V-109-R is a high-performance DC-DC converter with a wide input range and a compact size. It is a reliable device suitable for many different applications. The device operates over an 8 - 35V DC input range, providing an isolated, regulated, and adjustable output voltage from 0.1 - 6V at a current up to a maximum of 5A. The converter has built-in protections for short circuit, overload, and overtemperature, and its efficient design ensures low power consumption.The primary application field of the IEH48025A120V-109-R is industrial and telecom systems, instrumentation, and automotive. This model is made of high-temperature resistant materials and is designed to handle high-temperature environments. It is suitable for a wide range of operating temperatures, ranging from -40 to 125°C. It is also qualified for the commonly used industrial methods of temperature cycling, shock, and vibration.The working principle of the IEH48025A120V-109-R is based on the principle of DC-DC buck, boost, or buck-boost conversion. A buck converter reduces the input voltage to obtain a certain lower output voltage. In contrast, a boost converter increases the input voltage to get an output voltage slightly higher than the input voltage. A buck-boost converter is, as the name implies, a combination of the buck and boost converter, thereby allowing a certain output voltage or current to be generated, regardless of the input voltage or current level.The IEH48025A120V-109-R utilizes a synchronous rectification method and current mode control circuits to achieve power conversion. A synchronous rectification circuit is utilized to reduce the power consumption and improve efficiency. The current mode control circuit is used to speed up the response time of the system and enables quick and stable output voltage. The main components of the circuit include the transformer, switching transistors, rectifier, and control circuits. Depending on the type of converter, the transformer can be either a single or multiple winding type, while the components of the control circuit can consist of a CMOS or bipolar transistor, feedback resistors, and a reference voltage source.The IEH48025A120V-109-R is a highly versatile and efficient DC-DC converter, designed to meet the most demanding requirements of industrial and telecom systems, instrumentation, and automotive applications. Thanks to its wide input voltage range, high output current, and small size, the converter is an ideal choice for various DC voltage and current conversion projects.
