DC-DC converters are a type of power conversion system that is used to convert direct current (DC) voltage from one level to another. A DC-DC converter is usually used for isolated power distribution applications, such as powering electronic components from a distributed power source. The VWRBT2-D24-S9-SMT-TR is a specific product in the DC-DC converter category. This article discusses the application field and working principle of VWRBT2-D24-S9-SMT-TR.

Application Field

The VWRBT2-D24-S9-SMT-TR is a step-down DC-DC converter that operates from input voltages of 9 to 24 volts and provides an output voltage of 4.5V. It is designed to be used in applications which require precise control of output voltage and current, such as portable electronic equipment. The VWRBT2-D24-S9-SMT-TR is ideal for use in portable industrial, medical, test & measuring, and automotive applications.

The VWRBT2-D24-S9-SMT-TR is a robust power source with built-in protection features such as over temperature protection, input overvoltage protection, and short-circuit protection. It also has a wide operating temperature range of -40°C to +85°C, making it suitable for use in a variety of environmental conditions. The VWRBT2-D24-S9-SMT-TR is available in a compact surface-mount package, making it an ideal solution for space-constrained applications.

Working Principle

The VWRBT2-D24-S9-SMT-TR is a DC-DC converter that uses a switch-mode power conversion technique to convert direct current (DC) voltages from one level to another. It is designed to step down an input voltage of 9 to 24 volts to a preset output voltage of 4.5V. The working principle involves a circuit that contains a power switch, an inductor, and a capacitor, which work together to regulate and control the output voltage.

The power switch is used to alternately charge and discharge the inductor and capacitor, in order to convert an input DC voltage to a lower output voltage. The power switch is switched on and off at a high frequency, usually around 20 kHz, in order to produce a time-averaged output voltage. This allows for the conversion of the higher input voltage into a lower output voltage with minimal losses.

The VWRBT2-D24-S9-SMT-TR also incorporates an over-temperature protection circuit which shuts down the converter if the temperature exceeds a preset limit. This protection circuit prevents the converter from operating outside of its safe operating parameters by disabling the power switch if the temperature rises beyond a certain threshold. The VWRBT2-D24-S9-SMT-TR also includes a short-circuit and over voltage protection feature which prevents it from operating in an unsafe condition.

Conclusion

The VWRBT2-D24-S9-SMT-TR is a step-down DC-DC converter designed for use in a variety of applications. It operates from input voltages of 9 to 24 volts and provides an output voltage of 4.5V. It incorporates a number of protection features such as over-temperature, short-circuit, and overvoltage protection. The VWRBT2-D24-S9-SMT-TR is an ideal solution for use in portable industrial, medical, test and measuring, and automotive power applications.
