Working Principles

The ISL6536AIB operates as a dual-phase buck controller. It receives an input voltage and converts it into a regulated output voltage using pulse-width modulation (PWM) techniques. The feedback pins (FB1 and FB2) monitor the output voltage and adjust the duty cycle of the PWM signal to maintain the desired voltage level. The compensation pins (COMP1 and COMP2) help stabilize the control loop and prevent oscillations. The soft-start pins (SS1 and SS2) control the startup behavior of the voltage regulator, gradually ramping up the output voltage to prevent sudden voltage spikes.
