DC-DC Converters are components used to convert DC power from one voltage to another voltage. TEL 8-4813WI is a DC-DC converter by Murata Electronics Corporation which can convert an input of 8-48 Vdc and delivers a regulated output of 5Vdc up to 2A for system circuits. The TEL 8-4813WI offers excellent performance with high short circuit current protection and excellent transient response.

The application fields of TEL 8-4813WI are mainly in embedded systems such as industrial and communication control. It can also be widely used in areas such as mobile communication systems, computer systems for office or home use, self-serving kiosks, and medical instruments. Additionally, it is suitable for battery-operated systems requiring an operating voltage exceeding 48 Vdc.

TEL 8-4813WI is designed with an input stage consisting of a Schottky Diode and internal series regulator. The input stage protects the other stages by limiting the peak voltage and ensures that the input series regulator is always active. It also features an output stage consisting of a linear regulator circuit that is capable of providing a steady DC output with minimum 20% more current than the nominal output current.

The working principle of TEL 8-4813WI is based on the characteristics of the components and circuits it consists of. The input stage absorbs high frequency noise and passes the DC component to the output stage. It includes an output regulator circuit, which regulates the output voltage according to the input voltage and load conditions. It also features a high-frequency control circuit and an overcurrent protection circuit, which protect the TEL 8-4813WI from overcurrent or overload conditions. It also includes a power-on reset circuit and an EMI filter circuit to improve the anti-interference performance. Lastly, the output terminal features a short-circuit protection circuit which helps to protect the outputs when the short-circuit occurs.

In conclusion, TEL 8-4813WI is a DC-DC converter by Murata Electronics Corporation which can convert an input of 8-48 Vdc and deliver a regulated output up to 2A with excellent performance. It is suitable for embedded systems and battery-operated systems and its working principle is based on the characteristics of the components and circuits it consists of.
