Working Principles

The MIC23656FAYFT is a voltage regulator IC that converts an input voltage within the range of 2.7V to 5.5V into a regulated output voltage between 0.6V and 3.6V. It achieves this by utilizing a switching regulator architecture, which offers high efficiency and low quiescent current.

The device operates by continuously monitoring the output voltage through the feedback pin (FB) and adjusting the duty cycle of the internal switch accordingly. This control mechanism ensures a stable output voltage despite variations in the input voltage or load conditions.

Additionally, the enable pin (EN) allows for easy on/off control of the regulator, providing further power management flexibility.
