R-7215P Power Supplies - Board Mount

DC-DC converters are power conversion devices that convert one voltage level to another voltage level either step up (boost) or step down (buck) the level. Such converters are widely used in a variety of applications today, from consumer to industrial. The R-7215P DC-DC converter is an isolated, small-sized, and high power 15W DC-DC converter module that can achieve up to 91% of high efficiency. The module is designed for DC system with wide input voltage range of 4.5V to 36V. This makes it ideal for applications in power buses of industrial systems, transportation systems, and many other engineering applications.

The R-7215P features various control protocols such as voltage and current mode control. Voltage mode control allows for an easy response to load variations, faster transient response, and higher frequency operation. In addition, the module also contains a wide selection of input and output filters that increase the power line immunity, which enables use in automotive and other strong noise environment. The R-7215P module is also pin-compatible with a wide selection of RoHS compliant fixed input/isolated-output voltage modules, making it easier for system designers to select the power components they need.

The working principle of the R-7215P is simple but effective. First, the input voltage is rectified and filtered through the input capacitors and inductors. Then it is regulated with the primary control switch, which is driven by the PWM controller. This creates a pulsing DC voltage which then drives the transformer. The AC voltage that is created by the transformer is then regulated and rectified, and the output voltage from the converter is taken from the output capacitor.

The R-7215P module uses synchronous rectification, resulting in higher efficiency and better thermal control. Additionally, the module also offers remote sense with compensation, which ensures Vout is stable under varying load conditions. It also features low minimum on time, which allows for higher frequency switching and lower EMI noise.

In conclusion, the R-7215P is a powerful, efficient, and reliable 15W DC-DC converter module ideal for wide range of applications in power buses of industrial systems, transportation systems, and many other engineering applications. It features voltage mode control, wide selection of input and output filters, synchronous rectification, and remote sense with compensation, which provide superior performance and high power reliability.
