In the schematic analysis, this appears as two internal switches: a high-side NMOS (connected to the input voltage, $V_IN$) and a low-side NMOS (connected to ground). The inclusion of the low-side MOSFET is the primary driver of the device's high efficiency. When the high-side switch turns off, the low-side switch turns on, allowing current to recirculate through the inductor with minimal resistive loss ($I^2R$) rather than dissipating power across a diode's forward voltage drop. The schematic representation highlights this by showing the SW (Switch) node connected internally to the drain of both transistors, a configuration that demands precise dead-time control logic to prevent "shoot-through" (a condition where both switches conduct simultaneously, causing a short circuit). When the high-side switch turns off, the low-side
