Working Principle

The NCV4299D1 operates by sensing a voltage difference between two points: The input voltage and the output voltage. The device uses this difference between the two voltages to regulate and maintains the output voltage, regardless of the input voltage. This regulation occurs through the operation of an internal reference voltage and an internal error amplifier. The internal reference voltage is used to compare the output voltage with the reference voltage. The error amplifier is used to drive the P-channel MOSFET, which is used to regulate the output voltage. The P-channel MOSFET is switched on and off to adjust the output voltage, depending on the input voltage, load current, and reference voltage.
