DC-DC converters are widely used in a variety of applications, such as supplying power for computers, telecommunications equipment and electronics. The VI-21Z-CU is a DC DC converter that is unique in its design and operation. This article will discuss the application fields of the VI-21Z-CU and the working principle of the DC-DC converter.

The VI-21Z-CU is primarily used in system-level power-supply applications, such as applications that require higher efficiency and smaller size than standard switching regulators. As such, the VI-21Z-CU is especially suited to load applications where a wide input voltage range, low-output ripple, and maximum power are mandatories such as in portable systems, like notebook computers, industrial automation, and embedded systems.

The VI-21Z-CU is a voltage controlled, high-efficiency boost mode DC DC converter. This means that it maintains a constant output voltage regardless of fluctuations in the input voltage. The VI-21Z-CU utilizes a voltage-mode control scheme to achieve the desired performance. This scheme minimizes input voltage ripple and provides fast response to dynamic load changes.

The working principle of the VI-21Z-CU is quite simple. The input voltage is converted to a current-limited boost voltage by a power switch in the converter. This boosted voltage is supplied to the load through a Schottky diode. The power switch mode converts the high-frequency current fluctuations into voltage fluctuations, which are then filtered by the output capacitor to provide a steady output voltage. The output voltage is controlled by a voltage-sense circuit, which adjusts the duty cycle of the power switch to maintain a constant output voltage.

The VI-21Z-CU has an input range of 3.3V to 5V and a maximum output power of 21W. It also has a very high efficiency of up to 95%, which makes it more economical to use than many other DC-DC converters. Additionally, the module includes protection features such as short circuit protection, over-temperature protection, and over-voltage protection.

In conclusion, the VI-21Z-CU is an efficient and versatile DC-DC converter that can be used in many applications. It provides a wide input voltage range, high efficiency, and maximum power. Its voltage-mode control scheme ensures low-output ripple and fast response to dynamic load changes. The VI-21Z-CU’s protection features provide added safety and reliability.
