Line and Load Regulation and Efficiency Measurement Procedure
Set up the EVM as described in
Section 2.1
and
Section 4.1.2
.
Set the electronic load to draw 0A
DC
.
Increase V
IN
from 0V to 12V using a voltage meter to measure input voltage.
Use the other voltage meter to measure output voltage, V
OUT
.
Vary the load from 0 to 20A
DC
. V
OUT
must remain in regulation as defined in
Figure 4-2
.
Vary V
IN
from 4V to 16V. V
OUT
must remain in regulation as defined in
Figure 4-3
.
Decrease the load to 0A.
Decrease V
IN
to 0V.
