Introduction

DC/DC converters are widely used in industries and premises. They convert a dc input supply into a regulated dc output without the need of manually changing the switching frequency or the duty cycle. REC6-1209SRW/R8/A/CTRL is a type of dc/dc converter with a wide range of applications. In this article, we will discuss its application field and working principle.

Application Field

REC6-1209SRW/R8/A/CTRL can be used in a variety of power systems, such as telecom, industrial, automotive, and aerospace. It is a single output regulator with 80%-120% maximum input-to-output ratio. This makes it ideal for voltage boosting applications up to 6A. It also boasts a wide input voltage range, from 5V to 55V DC.Moreover, REC6-1209SRW/R8/A/CTRL is equipped with over-voltage, over-temperature, and over-current protection, making it highly suitable for industrial installations and in-vehicle electronic systems that require reliable and robust power supplies. It also features fast transient response and high efficiency, making it an ideal choice for applications that require precise voltage control and low power loss.

Working Principle

The working principle of REC6-1209SRW/R8/A/CTRL is based on the Buck-Boost topology, utilizing a Pulse-width Modulation (PWM) control mechanism. In this topology, the input voltage source is connected directly to the switching transistors and the output voltage is regulated by adjusting the duty cycle of the pulses.At low input voltages, the duty cycle is increased so that the average output voltage is higher than the input voltage. At high voltage input, the duty cycle is decreased so that the average output voltage is lower than the input voltage. This ensures that the output voltage is always regulated as per the setpoint, while maintaining the peak current within the safe operational range.The PWM control system also features advanced protection mechanisms, such as over-voltage, over-temperature, and over-current protection. It also implements inner current sensing and Master-Slave synchronization to optimize the system performance and extend its life.

Conclusion

REC6-1209SRW/R8/A/CTRL is a powerful DC/DC converter with a wide range of applications, such as telecom, industrial, automotive, and aerospace. It can be used for voltage boosting applications up to 6A and boasts a wide input voltage range of 5V to 55V DC. It is equipped with advanced protection mechanisms, such as over-voltage, over-temperature, and over-current protection, and its PWM control system ensures precise voltage control and low power loss.
