Working Principle

At the heart of the MIC2571-2BMM is a switching regulator and a configurable hardware interface. These components together provide a high efficiency and low noise solution for power supply applications. The regulator utilizes a pulse-width modulation (PWM) modulator to generate a digital signal to control the power MOSFET. This digital signal is generated by a voltage feedback loop that allows for precise voltage regulation. Once the voltage is set, the PWM signal is then used to control the switching speed of the MOSFET. This modulated signal is then passed through an output filter that further reduces the output noise. In addition to the output filter, the MIC2571-2BMM also has an integrated low-pass filter, which helps reduce input noise.
