Working Principles

The LTC3410BESC6#TRPBF is a synchronous buck regulator that uses a pulse-width modulation (PWM) control scheme to regulate the output voltage. It operates by switching an internal power MOSFET on and off at a high frequency. During the on-time, energy is stored in the inductor, and during the off-time, the energy is transferred to the output capacitor.

The feedback pin (FB) monitors the output voltage and adjusts the duty cycle of the internal switch to maintain a stable output voltage. The enable pin (EN) controls the regulator's operation, allowing it to enter a low-power standby mode when disabled.
