Working Principles
The LT8672IMS#TRPBF is a step-down DC/DC converter that utilizes a high-efficiency switching regulator to convert a higher input voltage to a lower output voltage. It employs a synchronous rectification topology to minimize power losses and maximize efficiency. The IC regulates the output voltage by adjusting the duty cycle of the internal power switch based on feedback from the FB pin. The soft-start feature gradually ramps up the output voltage during startup, preventing excessive inrush current. The synchronization capability allows multiple converters to operate in phase, reducing input ripple and improving overall system performance.
