MT20E-4805SI-W

DC DC converters are used to convert direct electrical current (DC) electrical power to another form of direct electrical power of various voltage, current, and power levels. The MT20E-4805SI-W DC DC converter is one such device that is designed to provide conversion of electrical power from one voltage level to another, while still meeting certain efficiency requirements. In this article, we will look at the application field and working principle of the MT20E-4805SI-W DC DC converter.

Application Field

The MT20E-4805SI-W is designed for use in a wide range of industrial, telecom, medical, and military applications such as office and home security systems, automotive and boat power systems, high-power aerospace and defense systems, telecom power, and medical electromechanical systems. It is capable of supplying up to 20A of continuous current over the entire output voltage range of 1.8V-48V, making it a versatile and powerful DC DC converter. The converter includes an onboard overvoltage protection circuit, temperature-controlled current limit circuit, and a soft-start feature that prevents large inrush currents from causing damage to the system.

The converter has an operating temperature range of -40° C to +105° C, which allows it to be used in a variety of tough industrial environments. Its high-efficiency design ensures minimal wasted power, while also providing excellent power-to-weight ratio and low EMI/RFI emissions. The unit includes input and output electrical protection, as well as overvoltage and overcurrent protection. It is RoHS compliant and can be used in a wide variety of industries and applications.

Working Principle

The MT20E-4805SI-W is a switching-mode DC DC converter, which means that it uses a switching transistor to turn the power conversion process on and off. The switching transistor is controlled by a control signal, which is used to create a square wave (a pulse signal).This square wave is then used to drive a transformer, which is responsible for performing the conversion from one voltage to another.

The conventional DC DC converter uses a single coil, whereas the MT20E-4805SI-W uses two coils, one primary and one secondary. The primary coil is energized by the control signal, which creates an alternating signal in the secondary coil. This alternating signal causes a voltage drop across the secondary coil, which is then rectified and regulated to get the desired output voltage and current.

The MT20E-4805SI-W has a very high efficiency rating of up to 94%, which maximizes power-to-weight ratio and minimizes heat generation. The converter also has many protections built in, including input and output overvoltage protection, overcurrent protection, and short circuit protection. Overall, the MT20E-4805SI-W is a powerful and efficient DC DC converter that is suitable for a wide range of industrial, telecom, medical, and military applications.
