Working Principles

The LTC4416IMS#TRPBF operates by controlling the gate voltage of an external N-channel MOSFET. When the input voltage is higher than the output voltage, the device turns on the MOSFET, allowing current flow. In this state, the voltage drop across the MOSFET is minimal, resulting in low power dissipation. If the input voltage drops below the output voltage or a fault condition occurs, the LTC4416IMS#TRPBF turns off the MOSFET, blocking current flow and protecting the circuit.
