Line/Load Regulation and Efficiency Measurement Procedure
Ensure that Load is set to constant resistance mode and to sink 0 A
DC
.
Ensure that the jumper provided with the EVM on J6 is present before V
IN
is applied.
Increase V
IN
from 0 V to 12 V. Use V1 to measure input voltage.
Remove the jumper on J6 to enable the controller.
Vary Load from 0 A
DC
to 20 A
DC
. V
OUT
must remain in load regulation.
Vary V
IN
from 8 V to 14 V. V
OUT
must remain in line regulation.
Put the jumper on J6 to disable the controller.
Decrease Load to 0 A
Decrease V
IN
to 0 V.
