Working Principles

The ISL6569CR-T operates as a synchronous buck voltage regulator. It converts the input voltage to a lower, regulated output voltage using high-side and low-side MOSFETs. The feedback pin (FB) monitors the output voltage and adjusts the duty cycle of the MOSFETs to maintain a stable output. The soft-start function gradually ramps up the output voltage during startup to prevent excessive inrush current.
