DC-DC converters are essential components in many electronic applications. They change the input voltage level of a power supply to match the different levels of electronic circuits. The VAT1-S24-D5-SMT-TR is an economical and reliable DC-DC converter manufactured by Vicor Corporation. It provides a regulated voltage output from a wide input voltage range while maintaining the ability to operate in a range of temperature and humidity conditions.

VAT1-S24-D5-SMT-TR is a medium power DC-DC converter with regulated voltage output from 6V to 24V and power output range from 5W to 150W. It works with an input voltage from a range of 15V to 280V DC. Its core component is an insulated-gate bipolar transistor (IGBT) which acts as a power transistor and offers excellent efficiency and superior power quality.

The VAT1-S24-D5-SMT-TR DC-DC converter is designed with conformity to the newest safety standards and CE/UL certification. It has a comprehensive set of protection features including over-current, over-voltage, and over-temperature protections. It also comes with a fan speed control that further enhances reliability by reducing the fan speed when input voltage is low or output current is steady and low.

The VAT1-S24-D5-SMT-TR offers high performance in applications such as industrial, medical, and network communication systems, telecommunications, DIN rail systems, and other applications where medium power and regulated voltage output and high reliability is important. It is useful for applications that require multiple output voltages with minimum added components.

The working principle of VAT1-S24-D5-SMT-TR is fairly simple. It utilizes an isolated flyback converter topology. When the base drive voltage (V_DRV) is applied, it creates a pulse-width modulated (PWM) signal to turn the IGBT on and off. The pulse-width modulated signal adjusts the duty cycle of the IGBT based on the input and output voltage levels. When the IGBT is turned on, it transfers energy from the input to the output side through a primary power transformer. When the IGBT is turned off, the transformer acts as an inductor to store the energy, and the output voltage is regulated by the flyback converter control circuitry. To protect against overvoltage, over-current and over-temperature conditions, the converter also incorporates advanced protection features.

In summary, the VAT1-S24-D5-SMT-TR is a reliable and economical DC-DC converter with high efficiency and excellent power quality. Its regulated voltage output from 6V to 24V and power output from 5W to 150W make it suitable for a range of applications. The insulated-gate bipolar transistor (IGBT) and the pulse-width modulated (PWM) control signal provide very reliable and accurate performance, while the comprehensive set of protection features ensures safe and secure operation.
