This test bench shows how the regulator reacts to changes in the input voltage (VIN) while the circuit is in steady state.
Output current is monitored while the regulator is trying to compensate for input voltage variation below or above
the nominal output voltage. The load is fixed formed by 4 LEDs driven by 1 A average current.

Notes:
BODY_DIODE is not a real diode but a Voltage Controlled Current Source which models the threshold and ON/OFF
states resistance.
For correct functioning of the controller, the simulation maximum time step cannot exceed 150 ns. Values above this
limit affect the internal clock generation.
