VEFT1-S12-S3.3-SMT-TR Power Supplies - Board Mount

DC DC converters are a type of electrical power supply that converts one form of energy into another form of electrical energy. The most common type of converter is the VEFT1-S12-S3.3-SMT-TR, which is used to convert electrical voltage from one level to another. In this article, we will discuss the application field and working principle of the VEFT1-S12-S3.3-SMT-TR converter.

The VEFT1-S12-S3.3-SMT-TR converter is a high-efficiency DC-DC converter used to step down voltage. It can provide up to 3.3 Watts of power conversion, making it a great choice for applications that require a high power density. The leading-edge technology used in this converter makes it extremely reliable, giving it an excellent service life. The small size of the VEFT1-S12-S3.3-SMT-TR converter makes it ideal for use in space-constrained applications.

The VEFT1-S12-S3.3-SMT-TR converter is used in a wide variety of applications. Common applications include industrial automation, medical, aerospace, and automotive electronics. The converter’s input can range from 5 V to 28V DC, and its output is adjustable from 0.5V to 7V DC, so it is suitable for a wide range of applications. The high step-down ratio of the converter efficiently reduces power consumption, making it suitable for energy-saving applications. The converter is also suitable for portable and wireless applications that require reliability and low-noise operation.

The VEFT1-S12-S3.3-SMT-TR converter works on a hysteretic control principle. This means that when the input voltage exceeds the minimum output voltage (or switching threshold), the converter begins to switch on. As the input voltage starts to decrease, the converter will switch off when the voltage reaches the switching threshold again. The output current fluctuates within the hysteresis loop, or dead band, of the converter, avoiding overshooting. This type of control ensures that the output voltage of the converter is stable, precise, and efficient.

The VEFT1-S12-S3.3-SMT-TR converter is designed to withstand high operating temperatures and provide fast transient response. It features a wide operating temperature range from -40°C to +105°C, enabling it to perform in challenging environments. The converter provides short circuit protection and undervoltage lockout (UVLO) to protect the system from damaging conditions. It also has a low standby power consumption to save energy in idle mode. The high efficiency of the VEFT1-S12-S3.3-SMT-TR converter enables it to provide a high power density even in a small form factor.

In conclusion, the VEFT1-S12-S3.3-SMT-TR is a high-efficiency DC-DC converter used for step-down voltage conversion. It is used in a variety of applications such as industrial automation, medical, aerospace, and automotive electronics. The converter works on a hysteretic control principle, which ensures that the output voltage is stable, precise, and efficient. The VEFT1-S12-S3.3-SMT-TR has a small size, wide temperature range, reliable operation, and fast transient response. All these features make it an ideal choice for space-constrained, energy-saving, and portable applications.
