Working Principles

The RT8555AWSC is a voltage regulator IC that converts an input voltage within the range of 2.7V to 5.5V to a regulated output voltage between 0.6V and VIN. It utilizes a switching frequency of 1.2MHz to efficiently step down the input voltage while minimizing power losses. The feedback pin (FB) monitors the output voltage and adjusts the duty cycle of the internal switch to maintain a stable output. The enable pin (EN) controls the operation of the IC.
