Working Principles

The LTC3410BESC6-1.5#TRPBF is a synchronous buck regulator that uses a pulse-width modulation (PWM) control scheme to regulate the output voltage. It employs a high-side N-channel MOSFET and a low-side P-channel MOSFET to achieve high efficiency.

When the input voltage is applied, the internal control circuitry generates a PWM signal that controls the switching of the MOSFETs. This switching action converts the input voltage to a regulated output voltage based on the feedback received from the FB pin.

The regulator continuously adjusts the duty cycle of the PWM signal to maintain the desired output voltage, compensating for changes in load conditions and input voltage variations.
