DC-DC converters are power conversion devices used for purpose of converting the input DC voltage level to a designated DC voltage level without relying on an AC mains source, either through voltage step-up or voltage step-down function. UWR-15/335-D24-C is a high performance isolated DC-DC converter, whose components have been integrated into a very small surface mount package. This converter can offer the benefits of high power density and efficiency while also providing an effective level of isolation and potential/noise suppression. UWR-15/335-D24-C\'s application field mainly consists of power supplies, battery charging systems, telecommunications devices, and other similar applications that require a DC-DC converter. It is also suitable for harsh environment operation, such as military and aerospace applications where voltage isolation and high reliability are essential.

Working Principle

The UWR-15/335-D24-C works on the same principle as most other DC-DC converters. In a nutshell, it utilizes an input voltage gain stage, followed by a voltage step-down stage, and a voltage regulation stage. The input voltage gain stage is responsible for boosting the input voltage, so that the final voltage is within the range of the output voltage level required. The voltage step-down stage steps down the input voltage to a predetermined value, allowing for a further voltage regulation stage to regulate the output voltage to its desired value. Finally, an isolation stage is used to prevent any current or voltage fluctuations from the input stage into the output stage and to ensure safety levels.

Input/Output Characteristics

UWR-15/335-D24-C features wide input voltage ranges from 4.5V to 32V and output voltage range from 0.6V to 15V. This translates to a wide input-to-output voltage ratio, which effectively allows the device to be applied into multiple application fields. Furthermore, its output current range reaches up to 2.3A with a high efficiency of up to 93%.

Protection Features

The UWR-15/335-D24-C also features high levels of protection to provide secure operation for all applications. It offers reverse current protection, overvoltage protection, overcurrent protection, undervoltage protection, short-circuits protection, input undervoltage lockout and remote control enable/disable (RS-232/RS-485) features. In addition, it has a wide temperature range of -40 to +105°C, which can meet the requirements of extreme temperature applications.

Conclusion

In conclusion, the UWR-15/335-D24-C is a high performance DC-DC converter that can be used in diverse application fields from power supplies, to telecommunications and military & aerospace applications. With its wide input/output voltage range and high efficiency, it offers a great performance to be utilized in multiple applications.
