Efficiency: Calculate the efficiency using the formula:

Verify that the efficiency aligns with design expectations across the specified operating conditions.

Ripple Voltage: Measure the output voltage ripple using an oscilloscope. Ensure that the ripple remains within acceptable limits, minimizing potential issues with downstream components. Generally, increasing the values of capacitor decreases ripple voltage.

Stability and Transient Response: Analyze the stability of the control loop by assessing the response to step changes in load or input voltage. Confirm that the buck converter maintains stable operation under dynamic conditions.

Switching Frequency: Measure the actual switching frequency and compare it with the designed frequency. Ensure that the converter operates within the specified frequency range.

Temperature Rise: Measure the temperature rise of critical components during prolonged operation. Verify that the implemented thermal management strategies effectively control temperature within safe limits.
