Working principle

The R2S12-1512/H is a non-isolated buck converter that utilizes a high frequency switching circuit that allows for a very high power conversion efficiency. The device also features integrated input current sensing and output voltage programming for easier connection and optimization of parameters. Internally, a field-effect transistor (FET) is responsible for controlling the current flow between the input and output. The FET is switched on and off by a pulse-width modulation (PWM) signal, which can be generated by a controller. This causes the current to be shifted from the input to the output at a given frequency in order to reduce the output voltage to the desired level.

The output voltage is controlled by an internal switching voltage-reference (VREF) circuit that is regulated by either an external resistor or an on-chip oscillator that can be programmed by adjusting the frequency. The integrated input current sensing means that the device can measure the amount of current flowing through the FET while switching and can be used to optimize the efficiency of the device for different applications. Aside from the output voltage and input current sensing, the device also features integrated features such as over-temperature protection and soft start for smoother starts.

Conclusion

The R2S12-1512/H is a very versatile non-isolated buck converter, which can be used in a variety of applications, ranging from industrial and automotive applications to consumer and medical applications. It features integrated input current sensing and output voltage programming, and also features other integrated features such as over-temperature protection and soft start for smoother starts. Overall, the R2S12-1512/H is an excellent choice for many different DC-DC conversion needs.
