8. Turn on the power supply.

9. Set the electronic load to a constant current between 0mA to 800mA.

10. Verify the second voltmeter reading is 12V ±0.6V.

Lab Measurements

The MAXREFDES112# design was verified and tested under full input range and different

output load conditions.

The power efficiency vs. load current is illustrated in Figure 2.

Data were gathered from MAXREFDES112D#. All versions perform similarly.

Figure 2. Power efficiency vs. load current.

Figure 3 display the output ripple at full load (ripple + spike is 110mV ) when the input is

24V.
