Working Principles

The MP2120DQ-LF-P is a voltage regulator IC that converts the input voltage to a regulated output voltage. It utilizes a switching mechanism to efficiently step down the input voltage to the desired output voltage level. The feedback voltage pin (FB) monitors the output voltage and adjusts the switching action to maintain a stable output. The enable pin (EN) controls the ON/OFF state of the regulator. Additional pins such as soft-start/tracking (SS/TR), compensation (COMP), and bootstrap capacitor (BOOT) provide further control and stability.
