R2S-1205

DC-DC converters are widely used in various applications, ranging from consumer electronics to advanced communication and industrial applications. The R2S-1205 is one such DC-DC converter family, manufactured by Richardson RFPD, that offers up to 600W of power with an efficiency up to 95.6%.

This article will discuss the application field and working principle of the R2S-1205 finite state machine (FSM) DC-DC converter series.

Application Field

The R2S-1205 family is ideal for use in distributed power architecture. It is particularly suitable for power systems which require high power, wide input range and tight regulation. Some of its important applications include distributed power systems, industrial automation, communication systems, automotive and consumer electronics.

With its wide input voltage range of 3V - 48V, the R2S-1205 can be used in both 12V and 24V distributed power systems. It also offers a tightly regulated output with very low noise and ripple (down to 10mV). The R2S-1205 is also very efficient, achieving up to 95.6% efficiency at full load, which makes it ideal for battery operated devices.

Moreover, the R2S-1205 series of converters offers a variety of power outputs to meet the needs of different applications. It is available in two different packages (Quarter Brick and Half-Brick) with output current levels up to 40A.

Working Principle

The R2S-1205 series of DC-DC converter is based on a finite state machine (FSM) topology. The basic building blocks of this topology are the FSM and the digital control module, which is responsible for controlling the input and output voltage by regulating the power transistor. The FSM is configured to provide the desired output voltage by adjusting the switching frequency of the power transistor.

The FSM is designed to reduce electromagnetic interference (EMI) while also maintaining high efficiency. This is achieved by using a pulse-width modulated (PWM) control technique which enables the operation of the power transistor in different modes at different switching frequencies. This results in higher efficiency, lower EMI and stricter voltage regulation.

In addition to that, the R2S-1205 series of converters also features several protection and monitoring features. These features includes over-voltage protection, over-current protection, output short circuit protection, and constant-voltage, constant-current limit. It also features a user-friendly graphical display and a tactile switching button for easy user interface.

Conclusion

The R2S-1205 series of DC-DC converters is a cost-effective solution for a wide range of applications that require high power, wide input range and tight regulation. Its advanced FSM topology enables efficient operation with very low output noise and ripple, and the protection and monitoring features make it suitable for many industrial and consumer applications.
