DC DC Converters

TMV 0505DHI is a DC-DC converter module with high power density. It is ideal for high power industrial applications such as adjustable voltage power supplies. The product can be used to convert a high current input voltage into a low output voltage of up to 5V with the power being limited to 20W.

Application Field

The TMV 0505DHI is suitable for a variety of industrial applications such as automotive electronics, telecom base station, Datacom systems, industrial equipment, control systems, medical instrumentation, computer systems, and military applications.

This DC-DC converter is also suitable for use in harsh industrial environments due to its wide input voltage range, over-temperature protection, and over-current protection. It also features an adjustable voltage mode and is equipped with a voltage monitor to ensure the output voltage always remains within the specified range.

Working Principle

The TMV 0505DHI operates by accepting input voltage from a direct current (DC) source (typically between 4V to 40V DC). The input voltage is then converted into a low output voltage (typically between 4V and 5V DC). The output voltage is adjustable depending on the amount of current drawn from the converter.

The TMV 0505DHI utilises an inductor to store energy from the input voltage during operation. A switching element, usually a MOSFET, is then used to switch the output voltage between different levels. As the voltage is switched, the magnetic field generated by the inductor is used to transfer energy to the output voltage. This process ensures that the output voltage remains within the required range.

The module also includes a voltage monitor which is used to continuously monitor the output voltage. If the voltage falls outside of the specified range, the monitor will automatically adjust the output voltage to ensure the output remains within the specified range.

The TMV 0505DHI is an efficient and reliable DC-DC converter. It is capable of delivering up to 20W of output power and offers over-temperature and over-current protection. This ensures that the device is optimized for use in harsh industrial environments.
