conditions for this system are
Input Voltage, Vin = 10 – 25V
Output Current, Iout = 0 – 52A
Output Voltage, Vout = 0.8 – 1.85V
Timing Diagram, Vin = 10V, Iout = 0, Vout = 1.45V
Timing Diagram, Vin = 10V, Iout = 10A, Vout = 1.45V
Timing Diagram, Vin = 10V, Iout = 20A, Vout = 1.45V
Timing Diagram, Vin = 10V, Iout = 30A, Vout = 1.45V
