Working Principles

The ISL6324CRZ-T is a dual-channel voltage regulator that utilizes a pulse-width modulation (PWM) control scheme. It regulates the output voltage by adjusting the duty cycle of the internal switches. The adaptive voltage positioning (AVP) feature dynamically adjusts the output voltage based on load conditions, improving transient response.

The IC incorporates overcurrent protection, which limits the output current to prevent damage to the circuit. It also includes thermal shutdown protection, which shuts down the regulator if the temperature exceeds a certain threshold.
