DC/DC converters provide the necessary regulated power supply regardless of whether the incoming power is from AC mains or DC sources. The VI-JT4-IY-B1 is a typical DC/DC converter with wide application field and high reliability. This technology can be used in industrial, communication, military and many other applications.

The VI-JT4-IY-B1 is a dc dc converter that achieves tight regulation, high efficiency and excellent transient response. It features a wide input voltage range from 9 to 75V and has an adjustable output voltage range of 3.3 to 34 V. Output current of 6A is also available when properly air-cooled. It integrates a current mode PWM controller and a MOSFET output stage. The onboard circuitry supports both constant voltage and constant current operation, and the digital soft-start feature enables rapid, reliable start up.

Working Principle:In order to understand the working principle of VI-JT4-IY-B1 DC DC converters in more details, it is important to understand the basics of how the voltage switching and isolation work. When the source input voltage is applied to the primary winding of the transformer, a secondary high voltage is generated. This high voltage is then converted to a low voltage by a full wave bridge rectifier. This low voltage is regulated by an error amplifier and fed back to the pulse width modulator (PWM). The PWM modulates the MOSFETs that are connected to the output of the transformer. As the duty cycle of the MOSFETs is varied, the output voltage is regulated.

The MOSFETs operate in a special manner to provide isolation between the input and output. The regulation is achieved by means of a feedback loop that modulates the primary switch duty cycle to maintain the regulated value. The secondary side of the transformer is shorted through diode bridge to transfer energy during high duty cycle operation and provides the desired isolation. This provides for a very small board area and a more efficient system.

Conclusion:The VI-JT4-IY-B1 DC DC converter is a reliable and efficient DC DC converter with a wide application field. The primary advantage of this technology is its robust design, which makes it particularly suitable for industrial, communication, military applications and more. It maintains tight regulation, high efficiency, and excellent transient response. The working principle of the VI-JT4-IY-B1 involves the use of MOSFETs in order to provide the necessary isolation between the input and output, and the PWM modulation to provide the desired voltage regulation.
