Measurement of RMS current of output capacitors

load. All the RMS currents are within the rating of the capacitor type indicated. This avoids

any component overstress that could affect the reliability and the expected lifetime of the

SMPS.

Dynamic load test

The dynamic load tests have been performed by varying the load on 3.3 V and 5 V outputs,

keeping the other outputs at full load. Varying the load on 3.3 V output, the following results

have been obtained:
