VI-22P-CX-S

DC DC Converters are electronic devices that can convert a varying voltage from a single direct current (DC) source into a regulated voltage or current. The VI-22P-CX-S is a type of DC DC converter that is used to step-up or boost the DC voltage from a single battery or solar cell to a higher, regulated DC voltage. The device has been designed for applications in portable applications such as battery powered tools and personal consumer electronics and is suitable for use in both lead-acid and lithium-ion battery systems.

Features

The VI-22P-CX-S offers a range of features which make it suitable for specific applications. It incorporates a synchronous P-channel MOSFET controller with over-current and over-temperature protection, reversible output protection and active current sharing circuitry that allow multiple converters to be run in parallel. The device is available in a wide variety of package sizes and is designed for surface mounting, allowing it to occupy minimal board space. The device also features built-in diagnostics, soft-start circuitry and a wide input voltage range, allowing it to be used in both low and high current applications.

Working Principle

The VI-22P-CX-S is a type of DC DC converter known as a Buck-Boost Converter. This is a type of device that is capable of both boosting and bucking the input voltage dependent on the output voltage requirements. For example, if the output voltage requirement is lower than the input voltage, the device will buck or reduce the input voltage to the desired output. Conversely, if the output voltage is higher than the input voltage, the device will boost the input voltage to the desired output. This device uses a transformer to provide galvanic isolation between the input and output, enabling the user to safely step up or down the voltage while providing a high level of safety.

The VI-22P-CX-S also utilizes a feedback loop to provide precise, adjustable output voltage. This feedback loop involves measuring the output voltage with a voltage divider and comparing it to a reference voltage, generating an error signal which is then used to adjust the output voltage. This allows for a very accurate and precise output voltage, making it suitable for applications where tight tolerances are needed.

Application Fields

The VI-22P-CX-S has a wide range of applications in portable battery systems and personal consumer electronics. The device is suitable for use in both lead-acid and lithium-ion battery systems and incorporates protection features for added reliability. It is ideal for applications such as battery powered tools, portable medical equipment, portable lighting and consumer audio and video devices. The device is also suitable for use in automotive applications such as electric vehicles (EVs) and hybrid electric vehicles (HEVs).

Conclusion

The VI-22P-CX-S is a DC DC converter designed for use in portable battery systems and consumer electronics applications. The device is capable of boosting or bucking the input voltage dependent on the output voltage requirements and features protection and diagnostic features to ensure reliability and safety. The device has a wide range of applications in both lead-acid and lithium-ion battery systems, as well as in automotive applications. This makes the VI-22P-CX-S an excellent choice for designers looking for a cost-effective and reliable DC DC converter.
