Working Principles
The ISL6614CR is a synchronous buck regulator that converts a higher input voltage to a lower output voltage. It utilizes high-frequency switching to efficiently regulate the output voltage. The feedback pin (FB) monitors the output voltage and adjusts the duty cycle of the internal switches to maintain the desired voltage level. The compensation pin (COMP) ensures stability by controlling the loop response. The soft-start pin (SS) gradually ramps up the output voltage during startup to prevent excessive inrush current. The enable pin (EN) allows for on/off control of the regulator.
