DC-DC converters are devices that convert the direct current or DC signal from one voltage level to another. The RTD-2412/P is an efficient, robust, and reliable DC-DC converter that has a wide variety of applications. In this article we will be exploring the application field and working principle of the RTD-2412/P DC-DC converter.

Application Field

The RTD-2412/P DC-DC converter is a highly integrated step-down DC-DC converter that was designed for use in communications, data processing, automotive electronics, industrial control, and other systems requiring a reliable power source. The RTD-2412/P is capable of operating at input voltages from 6.5V up to 26V and provides a continuous output current of up to 24A. Its wide operating input voltage range and its output current capability make it ideal for use in applications where high performance, high reliability, and high efficiency are necessary.

The RTD-2412/P is the latest in a series of high-performance, low-cost, electrically efficient DC-DC converters from RECOM. Its main features include wide input voltage range, low profile DIP package, built-in synchronous rectification, positive (+) on-off logic control, no external components required, thermal protection, and high efficiency over a wide operating temperature range.

The RTD-2412/P DC-DC converter makes an excellent choice for a variety of applications, from low-voltage control systems and electric vehicles to solar and wind power systems and industrial automation. It is also suitable for applications that require high efficiency and low power dissipation such as embedded control systems and notebooks.

Working Principle

The RTD-2412/P converter is a synchronous buck converter designed to convert an input voltage of 6.5V to 26V into a fixed output voltage of 1.2V, 3.3V, or 5V as determined by the user. The converter achieves high efficiency over the entire input voltage range by using synchronous rectification technology. The synchronous rectification uses the body diode of the high-side MOSFET as a synchronous rectifier, eliminating the need for a charge pump driver. This significantly reduces the power dissipation, making the converter\'s efficiency much higher than conventional diode rectified buck converters.

The RTD-2412/P converter\'s output voltage is regulated by a feedback pin that allows it to adjust the output voltage according to feedback from the load. This feedback voltage is compared to a reference voltage, and the difference is used to control the duty cycle of the MOSFET switch, which in turn adjusts the output voltage. The feedback voltage is also compared to an over-voltage/under-voltage threshold to ensure safe operation of the converter.

The converter also features an enable pin which can be used to put the converter in a low-power sleep mode or to completely disable the converter, allowing it to be used in systems where power conservation is key. The enable pin can be used to completely shut down the converter when the system is in a standby or shutdown state, significantly reducing the power consumption of the system.

The RTD-2412/P is protected by a variety of features including over-temperature, short-circuit, and under-voltage protection which ensure safe and reliable operation of the converter. The converter also has an input voltage protection feature which prevents the input voltage from rising above the specified maximum level, providing an added layer of protection for the converter.

Conclusion

The RTD-2412/P DC-DC converter is a reliable and efficient solution for a wide variety of applications. Its wide operating input voltage range, robust output current capability, and efficient synchronous rectification make it an excellent choice for applications that require high performance and high reliability. Its built-in protection features provide an added layer of safety for the system and ensure reliable operation. The RTD-2412/P is an ideal choice for applications requiring reliable, high-performance power conversion such as embedded control systems, electric vehicles, solar and wind power systems, and industrial automation.
