The VI-26J-MV is designed with a synchronous step-down converter. It is a low-cost design option ideal for automotive, computer, and telecom applications. It offers high efficiency, high ripple performance, fast transient response, and a wide input voltage range. It can also operate in a wide temperature range. The device is capable of handling transient overloads of up to 400%.

Working Principle

The VI-26J-MV is a synchronous step-down DC/DC converter. It works by converting an input voltage of VIN into an output voltage of VOUT. The circuit works by converting the input voltage to an intermediate voltage that is slightly lower than the desired output voltage. The output voltage is then generated by the DC-DC converter. The output voltage is generated using an internal switch control loop that is designed to minimize output ripple and optimize efficiency.

To ensure the most efficient operation, the circuit is designed with an internal MOSFET switch, which can be used to directly control the output voltage. This switch is controlled by a Pulse Width Modulator (PWM), which is responsible for creating a series of pulses that are used to regulate the output voltage. This PWM is also responsible for providing the desired voltage ripple performance. The circuit also includes an inductor and capacitor to ensure smooth current flow and for filtering out any noise that may be present on the input line.

Conclusion

The VI-26J-MV is a high-efficiency DC/DC converter suitable for a wide range of applications. It offers an excellent combination of features, including a wide input voltage range, high efficiency, and excellent ripple performance. Additionally, it is a low-cost option that is optimized for size-constrained applications such as automotive, computer, and telecom.
