Working Principle

The V72A15T400BL uses a buck-boost topology to convert the input voltage into the output voltage. The V72A15T400BL is equipped with a power MOSFET switch, which is controlled by a PWM signal to convert the input voltage to the desired output voltage. The PWM signal is generated by a control circuit, which compares the feedback voltage from the output voltage with the reference voltage. When the output voltage is lower than the reference voltage, the power MOSFET switch will conduct for a certain time period; when the output voltage is higher than the reference voltage, the power MOSFET switch will be in an off-state for a certain time period. This on-off process will create a pulsating voltage at the output which is equal to the desired output voltage.

Conclusion

The V72A15T400BL is a highly reliable DC DC converter with wide input voltage range and rated output power of 15W. It is suitable for various power delivery applications such as high current applications, led lighting, communication systems, low voltage applications and low noise power supplies. The V72A15T400BL uses a buck-boost topology to convert the input voltage to the output voltage, with a power MOSFET switch controlled by a PWM signal that creates a pulsating voltage at the output which is equal to the desired output voltage.
