It also offers excellent transient response with an external compensation network.The REC5-0515SRW/H2/C/M also has input transient protection for I/O short-circuit protection, and a built-in thermal shutdown. Additionally, it features a dielectric isolation of 1500Vdc. Typical applications include supplies for TI converters, Industrial control circuits, Ethernet hubs, test & measurement, field instruments, UPS systems, and motor controllers.

Working Principle

The REC5-0515SRW/H2/C/M uses a buck converter design, which follows the basic concept of a DC-DC converter but with a much higher efficiency. In conventional buck converters, the high side switch, as well as the low side switch, is active only during certain intervals of time and triggered by an internal oscillator.The back-end of the converter features an internal NPN transistor and a low pass filter capacitor. The oscillator controls when the high side and low side switches are turned on and off to create oscillations and create an output voltage. The frequency of the oscillator is determined by the external components and the voltage is regulated with voltage feedback via a voltage divider.The buck converter is powered by the input voltage and the rest of the components work together to adjust the voltage output, depending on the load and the desired voltage. The output voltage of the REC5-0515SRW/H2/C/M is regulated to the optimal level, regardless of load, by controlling the on and off times of the high and low side switches.The REC5-0515SRW/H2/C/M provides excellent performance for circuits requiring high efficiency, reliability and precision voltage regulation. These features are essential when used in a variety of harsh and industrial environments such as those requiring an output voltage ranging from 5.0V to 15.0V. Overall, the REC5-0515SRW/H2/C/M is an essential component of any system that requires high-efficiency DC/DC conversion. Its low profile design is easy to use and is a reliable choice for industrial applications.
