Working Principles

The MIC2194YM is a voltage regulator that utilizes a synchronous buck converter topology. It operates by converting the input voltage to a regulated output voltage with high efficiency. The device uses pulse-width modulation (PWM) to control the switching of an internal power MOSFET, which regulates the output voltage based on the feedback received from the FB pin. The enable pin (EN) provides control over the device's operation, allowing for power-saving modes when not in use.
