Working Principles

The 72V281L15TFI8 operates based on a voltage regulation principle known as linear regulation. It uses an internal reference voltage and feedback mechanism to maintain a constant output voltage despite variations in the input voltage.

When the input voltage is applied, the IC compares it with the internal reference voltage. If the output voltage drops below the desired level, the feedback mechanism adjusts the internal circuitry to increase the output voltage. Conversely, if the output voltage exceeds the desired level, the feedback mechanism reduces the output voltage.

This continuous monitoring and adjustment process ensures that the output voltage remains stable and within the specified range.
