Working Principle

X4163PIZ-2.7A utilizes a pulse width modulation (or PWM) voltage regulator. The voltage is regulated by the width of a digital pulse in the PWM controller. The PWM controller adjusts the width of the pulse, depending on the feedback it receives from an external sensing element. The feedback element is typically a voltage divider or a resistor in series with the output voltage. When the feedback element measures a voltage that is different from the desired value, it will adjust the width of the pulses to bring it closer to the desired output voltage.

The PWM controller then generates a pulse to control the duty cycle of switching transistors in the regulator, which in turn affects the output voltage. Each pulse the PWM controller sends will cause the output voltage to go up, and when the pulse goes away the output voltage drops. By repeating this process, it allows for a stable output voltage even when experiencing fluctuating inputs.

The X4163PIZ-2.7A also includes other features such as over-voltage, over-temperature and over-current protection, as well as current limiting. These features provide the user with extra protection and peace of mind that their device is running safely.
