Working Principles

The LT3748MPMS#TRPBF is a step-down DC/DC converter that efficiently converts a higher input voltage to a lower output voltage. It utilizes a switching regulator topology to achieve high efficiency power conversion. The input voltage is connected to the VIN pin, and the desired output voltage is set using an external resistor divider connected to the FB pin. The SW pin is responsible for connecting the switch node to the inductor and capacitor, enabling energy transfer. The internal control circuitry regulates the duty cycle of the switch to maintain the desired output voltage.
