Working Principle of ISL6405EEBZ-T

The ISL6405EEBZ-T is based on the Buck-Boost switching regulator topology, which is a type of circuit that can convert source voltages that are both higher and lower than the output voltage, while delivering an acceptable amount of power to the load. The ISL6405EEBZ-T includes both a Buck and a Boost converter, which are connected in parallel. The Buck converter operates when the input voltage is higher than the output, while the Boost converter operates when the input voltage is lower than the output.

The ISL6405EEBZ-T employs a Pulse Width Modulation (PWM) switching technique for conversion. This technique involves the generation of high frequency pulses with varying duty cycles, which is then used to control the power delivery from the source voltage to the output voltage. This PWM modulation process is controlled by an internal oscillator inside the device, which is connected to a voltage feedback loop to monitor the output voltage. The output voltage is then compared to a reference voltage, and the duty cycle is adjusted in order to maintain the required output.
