Working Principles
The ADP2114ACPZ-R2 is a dual output buck regulator that converts an input voltage within the range of 2.7V to 5.5V to adjustable output voltages between 0.6V and 3.3V. It utilizes a high-frequency switching technique to achieve high efficiency power conversion. The regulator operates by controlling the duty cycle of the internal switches, which in turn regulates the output voltage. The soft-start feature ensures a gradual ramp-up of the output voltage during startup, preventing excessive inrush current. Synchronization capability allows multiple regulators to operate in phase, reducing noise and improving overall system performance.
