THN 30-1211

DC DC Converters

A DC-DC converter is a device that is capable of converting direct current (DC) electrical power from one voltage level to another voltage level. This is especially useful when both the input and output of a device is DC and when a product requires different power levels. The THN 30-1211 is a step down DC-DC converter that is designed for applications that require an output voltage lower than the input voltage. This article discusses the application field and working principle of the THN 30-1211 converter.

Application Field

The THN 30-1211 converter is designed with a wide range of applications in mind, specifically for products that require a regulated output voltage at a lower level than the input voltage. It is suitable for use in applications which require a low noise, adjustable or programmable DC voltage and current. The output voltage can be adjusted between 0.8V to 16V and the input voltage ranging from 8V to 40V. It has a wide operating temperature range in industrial and automotive applications, up to 100℃.

Working Principle

The THN 30-1211 converter uses a switching regulator technique to step down the input voltage. This technique uses a transistor switch in the control loop to regulate the output voltage to a desired level. When the switch is in the "on" state, the input voltage is applied to the inductor, charging the inductor with current and storing energy in the form of a magnetic field. When the switch is flipped to the "off" state, the stored energy is released into the output circuit and current flows in the output circuit. By alternating between the "on" and "off" states, the integrated circuit controls the output voltage. The output voltage can be adjusted by changing the duty cycle or frequency. The THN 30-1211 also has advanced features such as over-voltage and over-current protection for improved reliability.

Conclusion

The THN 30-1211 is a DC-DC step down converter designed to regulate output voltage at a lower level than the input voltage. It can be used in a variety of applications, such as those requiring a low noise, adjustable or programmable DC voltage and current. The output voltage can be adjusted between 0.8V to 16V and the input voltage ranging from 8V to 40V. The THN 30-1211 converter uses a transistor switch to regulate output voltage and features advanced features such as over-voltage and over-current protection.
