DC/DC Converters: R2D12-1205/H-R Application Field and Working Principle

DC/DC converters are products that convert a DC source into a different type or form of DC current. The R2D12-1205/H-R is a type of DC/DC converter for use in medium- to low-power applications. Its main application field is providing an isolated DC/DC voltage conversion from a wide range of input sources, such as an automotive backup system, to a more specific power requirement, such as powering an industrial logic board. This device is also suitable for other applications, including replacing expensive batteries and providing power to start high voltage automatic machines.This device has a minimum input voltage of 3 V and a maximum input voltage of 48 V, typical for automotive applications. It features an output power range of up to 124 mW and an output voltage of 3.3 V or 5 V (depending on the model). Additionally, it has an internal shutdown voltage of 43 V (for the highest output power), and carries a built-in over-voltage protection.Its working principle is fairly simple, yet effective. The source voltage is regulated by the input filter capacitor, providing an output terminal that\'s to be connected to the load. A bipolar transistor, or MOSFET, is used for amplifying the source voltage and controlling the power conversion. The transistors allow for current flow from the collector to the emitter. Through the transistor, the output voltage is regulated via the feedback loop and voltage-controlled oscillator (VCO). The oscillator is adjusted to maintain the output voltage via the feedback loop.The R2D12-1205/H-R is used in multiple applications due to its high efficiency, wide temperature range, and excellent performance. Its efficiency rate is as high as 94.7%, and can be used in temperatures ranging from -25°C to 70°C. Furthermore, its low ripple/noise and built-in short circuit and overload protection make it the ideal choice for many implementations.In summary, the R2D12-1205/H-R is an ideal choice for medium to low power DC/DC voltage conversion needs. Its features, such as its wide operating voltage range, high efficiency, and wide temperature range, make it very attractive to users. Its working principle is also simple-yet-effective, and its short circuit and overload protection, as well as its low ripple/noise, make it highly reliable for many applications.
