DC/DC converters are an important component of most power electronics systems. DC/DC converters are used to convert DC input power into various output power voltages, currents, and frequencies. These converters are available in many different configurations and power capacities.

The VI-24W-CY-F4 is a 24V, 12A DC/DC converter that provides reliable power conversion for many applications. It is a non-isolated buck-boost converter with a switching frequency of 400KHz. As a compact and cost-effective solution, the VI-24W-CY-F4 is suitable for a wide range of applications.

The VI-24W-CY-F4 supports a wide input voltage range from 13 to 36 VDC and has adjustable output voltage range from 4 to 24V. It also has a wide input range, peak efficiency of 88%, built-in current limit, short circuit protection, output over-voltage protection, and over-temperature protection.

The VI-24W-CY-F4 employs an embedded micro-controller for optimum efficiency and effectual results. The controller allows for an adjustable output voltage with PWM (Pulse Width Modulation) control. This allows for more accurate voltage control and maximum efficiency. The peak efficiency is maintained over a wide load range due to its constant-frequency control.

The VI-24W-CY-F4 operates in a buck-boost mode of operation. When the input voltage is lower than the output voltage, the converter operates in the buck mode and increases the voltage. When the input voltage is higher than the output voltage, the converter operates in the boost mode and decreases the voltage.

The operating principle for the VI-24W-CY-F4 is as follows: for the buck mode, an internal high-side MOSFET switch is turned on and an inductor is used to store energy. After that, another MOSFET switch at the output stage is turned on and the energy is released into the output load. The output load current then begins to flow, and the output voltage is regulated via feedback control. The output current is regulated by comparing the feedback signal to the reference voltage.

For the boost mode, an internal high-side MOSFET switch is turned on and an inductor is used to store energy. The stored energy is then released to the output stage, causing an increase in the output voltage. Then, the PWM control adjusts the duty cycle of the internal switches, and the output current is regulated by comparing the feedback signal to the reference voltage. Thus, the output voltage is regulated and stabilized.

The VI-24W-CY-F4 is ideal for a wide range of applications including automotive, telecommunications, medical equipment, industrial applications, and renewable energy systems. It is an efficient and cost-effective solution for DC/DC conversion needs.
