DESCRIPTION
Demonstration circuit 1414B-B features the
LTM
mode step-down power module. The input voltage range
is 5V to 28V with a jumper selectable output voltage
from 0.6V to 5V. The rated load current is 12A, although
derating is necessary for certain V
conditions. The PLLIN pin supports synchronizing the
μModule
pin allows the user to program output ramp-up and ramp-
down rates which may coincidentally or ratiometrically
