VI-BNR-CV-F2

DC DC Converters

DC-DC converters are widely used in a variety of applications where the voltage level needs to be changed. This can be done either by increasing or decreasing voltage from one level to another. For example, in modern electronic devices such as laptops, phones and tablets, their internal circuitry runs primarily on 3.3/5v which requires a DC-DC converter to step-down the 12/24 V battery input voltage.

VI-BNR-CV-F2 Application Field and Working Principle

The VI-BNR-CV-F2 is an integrated DC-DC converter designed to provide a stable output voltage and a wide range of current ratings at very high efficiency levels. The device is capable of generating a maximum output current of up to 50A. It is commonly used in automotive, industrial, LED and other applications that require a wide input voltage range.

The VI-BNR-CV-F2 utilizes a buck-boost circuitry, both step-up and step-down conversion is possible, and it is capable of conveying input voltages from as low as 4.5 V up to 30 V. It operates by taking the input voltage, storing it in the integrated inductor and then releasing it to the output voltage at the desired voltage to meet the output requirements.

The key feature of this IC is the integrated chronopotentiometric-mode (CPT) control circuit, which helps to achieve higher efficiency and better regulation performance compared to traditional PWM buck-boost design. The CPT control system provides the highest efficiency performance with minimal ripple, thus providing excellent voltage regulation. The integrated active current sensing helps to maintain the desired output current regardless of the input voltage or output load.

Overall, the VI-BNR-CV-F2 is an excellent option for a variety of applications, as it can provide a wide range of output voltages and current ranges. The integrated CPT control system helps to maintain excellent regulation performance at high efficiency. It is widely used in automotive, industrial and LED applications.
