Working Principles

ISL6556ACRZ-T operates based on a pulse-width modulation (PWM) control scheme. It regulates the output voltage by adjusting the duty cycle of the internal switching transistor. The feedback pin (FB) monitors the output voltage and compares it to a reference voltage, generating an error signal. This error signal is then used to adjust the duty cycle and maintain the desired output voltage.
