DC to DC converters are commonly used in portable electronics such as laptops, handheld devices and mobile phones. In order to keep the circuit safely within the regulated voltage range the converter must provide a precise control of output voltage and current. The TSRN 1-2433SM from Texas Instruments is a DC to DC converter that combines a high level of accuracy (0.3%) with a low voltage drop (0.4V). It offers a wide range of features such as wide input voltage range (6V to 36V), intelligent thermal management, integrated safety feedback, and programmable soft-start and overload protection.

The TSRN 1-2433SM uses a synchronous buck converter architecture with two MOSFETs operating in synchronism to regulate the output voltage. The circuit works through continuous power conversion of the input voltage to a regulated output voltage. The control of the output voltage is achieved by driving the two MOSFETs with a common square wave signal. When the square wave has a high voltage, one of the transistors is switched to the highest state, while the other is switched to the lowest state. This causes a current to flow through the inductor, charging the output capacitor and providing the output voltage as needed.

The TSRN 1-2433SM has an integrated safety feedback which provides current limit protection to prevent the output from exceeding a preset limit. It also protects the MOSFETs and other components from short circuit and over temperature conditions. The synchronous buck architecture enables the converter to efficiently convert the voltage while minimizing power loss. It also reduces the power dissipation at higher currents improving overall efficiency. The TSRN 1-2433SM also supports programmable soft-start and overload protection features which help protect the circuitry from inrush current, transient voltage and other abnormalities.

The TSRN 1-2433SM is suitable for wide range of applications such as portable electronics, automotive, and factory automation. In portable electronics, it is used to ensure steady power supply while the voltage of the supply is varying. In automotive applications, it is used in power supply systems. And in factory automation applications, it is used for powering control circuits and other industrial equipment.

In summary, the TSRN 1-2433SM is a highly efficient DC to DC converter suitable for range of applications. It offers a wide input voltage range, a low voltage drop, a high level of accuracy and integrated safety features for protection of the circuit components.
