Working Principle

The LM3671MF-2.5 works by using a two-stage topology for voltage regulation. The first stage is an oscillator that creates an alternating voltage waveform. This waveform is used to regulate the output voltage of the device by switching the input voltage on and off. This switching operation is controlled by an error amplifier. The error amplifier compares the output voltage of the device to an internal reference voltage. If the output voltage is greater than the reference voltage, the oscillator decreases the duty cycle, resulting in a decrease in the output voltage. Conversely, if the output voltage is lower than the reference voltage, the oscillator increases the duty cycle, resulting in an increase in the output voltage. This feedback mechanism ensures that the regulator is able to maintain a regulated output voltage despite fluctuations in the input voltage.
