Under the application conditions of 3.3V input and 0.8V/20A output, the output capacitors of buck1-4 in TI reference design are all configured with 1210/47uF * 3. What is the reason for choosing such a large margin? Because if calculated based on a single 5A output current, it seems that a single 22uF can also meet the design requirements. In this case, can the capacitance of the output capacitor be optimized to 22uF * 4?
