DC DC Converters

DC DC converters are electrical devices used to convert a direct current (DC) input to a higher or lower DC output voltage. Many designs are available to suit various applications, including step-up, step-down and buck-boost, single or multi-input, isolated or non-isolated, maximized efficiency or reduced size. One such device is the VI-24V-IW-F1.

VI-24V-IW-F1 Application Field
The VI-24V-IW-F1 is a two-wire dc-dc converter used primarily in closed-loop digital power control systems. It delivers 24V at up to 50W and is designed specifically to help reduce time-to-market for IoT (internet of things) applications, including industrial, commercial and consumer applications. The module is designed to be integrated directly into a circuit board with an on-board regulator providing up to 5A of continuous current.

VI-24V-IW-F1 Working Principle
The working principle of the VI-24V-IW-F1 is that it takes the 24V input voltage from the power supply and uses it to step down the voltage to the desired output voltage. This is achieved by utilizing a powerful, efficient full-bridge resonant converter architecture with an integrated control loop and a wide range of driver capability. This provides constant current or voltage output, ensuring a highly reliable and stable output.

The full-bridge converter circuit includes a half-bridge converter, two synchronous rectifiers and two capacitors. The half-bridge converter generates two alternating voltage waves which are passed to the two synchronous rectifiers, which convert the alternating voltage to the desired DC voltage. The two capacitors provide a filtering effect, allowing the device to maintain its output voltage for a set amount of time. The device also utilizes an integrated microcontroller-based control loop to constantly monitor the output voltage to ensure it remains constant.

The VI-24V-IW-F1 is highly efficient and has a wide operating temperature range of -40°C to +85°C. It also provides a number of safety features, including over-current, over-voltage, over-temperature and short-circuit protection. This helps ensure the device will consistently perform reliably in any application.

Conclusion
The VI-24V-IW-F1 is a highly efficient and reliable DC DC converter designed for use in closed-loop digital power control systems, such as IoT (internet of things) applications. It is capable of step-downing 24V input voltage to a desired output voltage and is designed with a powerful, efficient full-bridge resonant converter architecture and an integrated control loop. Additionally, it contains a number of safety features to ensure reliable performance.
