DESCRIPTION
Demonstration circuit 1414 features the LTM
a high efficiency, high density switch mode step-down
power module. The DC1414A accepts an input voltage from
5V to 20V to deliver a jumper selectable output voltage
from 1.2V to 5V at up to 12A. As shown in the data sheet,
derating is necessary for certain V
conditions. The LTM4601A allows the user to program
output ramp-up and ramp-down through the TRACK/SS pin.
The output can be set to coincidentally or ratiometrically
