Working Principles

The LTC1430CS#TRPBF operates as a step-down switching regulator. It converts a higher input voltage to a lower output voltage by rapidly switching the input voltage across an inductor and then filtering it to obtain the desired output voltage. The feedback pin (FB) is used to regulate the output voltage by comparing it with a reference voltage. The control circuitry adjusts the duty cycle of the switching transistor to maintain the desired output voltage.
