DC DC Converters

A DC-DC converter is a type of power converter which converts a direct current (DC) power supply to a different DC voltage level. These converters are used in a wide range of products such as computers, electronic appliances and automotive electronics. There are two main types of DC-DC converters: voltage converters and Buck converters. The main difference between the two is the way they convert the voltage.

MI-J21-IA Application Field and Working Principle

The MI-J21-IA is a DC-DC voltage converter specifically designed for industrial applications. It is an isolated voltage converter which can convert 12V/24V input voltage levels to a 5V DC voltage output. It has a power output of 10W and an efficiency of more than 85%. The MI-J21-IA is ideal for applications which require a low and regulated output voltage level, such as in the automotive, industrial and medical sectors.The MI-J21-IA is equipped with a wide range of features, such as a wide input voltage range, a wide operating temperature range, overvoltage/short circuit protection and a built-in EMI filter. It also features a low standby power consumption and a high reliability and long working life. The working principle of the MI-J21-IA voltage converter is based on an isolation concept. It converts the input voltage level to a defined output voltage level with the help of an isolated switching topology. The converter contains two power transformer coils that are wound in series, one connected to the input voltage and the other to the output voltage. The voltage is then switched to the output side with the help of two power FETs (Field Effect Transistor) that are connected to the transformer coils. The FETs are triggered by a control circuit which is composed of a microchip and other components. The MI-J21-IA converter also features a built-in electro-magnetic interference (EMI) filter which helps in suppressing the high frequency switching noise. This enables the converter to produce an output voltage that is more stable and reliable. In conclusion, the MI-J21-IA DC-DC voltage converter is an ideal choice for applications that require a precise and reliable output voltage. Its excellent features, such as wide input and operating temperature ranges, high efficiency and a built-in EMI filter make it a valuable alternative for various industrial, automotive, and medical applications.
