Load step

9/13

The SMPS meets the specification with efficiency better than 80% at any input voltage

value, as shown in Table 4.

Load step

This SMPS has been designed to operate under two conditions: standby and full load. In

Figure 5 and Figure 6 show the outputs voltages during load steps from standby and full

overshoot is present during load transient. The same test has been done to show the

Table 4.
