Moreover, its PWM output frequency can range from 2 MHz to 16 MHz.

Working Principle

The ISL6455AIRZ-T5KS2698 is designed to control the voltage output in a variety of applications. Its primary function is to regulate the output voltage to a precise level, regardless of the input voltage variations. This is achieved by first measuring the input voltage and converting it to a stream of pulses. The output voltage is then determined by the duty cycle of the pulses, giving rise to the PWM mode. The output voltage is then regulated and monitored by comparing it to the reference voltage set by the user. If the regulated voltage deviates from the reference voltage, the voltage control circuit will adjust the duty cycle accordingly. This is accomplished by varying the gate drive of the MOSFET switch element, which results in either an increase or decrease in output voltage. This process is repeated constantly to ensure that the voltage output remains within the specified range.
