4601AEV, 

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

, V

OUT

, and thermal 

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

track with another voltage rail. This board also supports 

demonstration of the output voltage margining function 

by ±5% from nominal which is determined by the state of 

the MARGN0 and MARGN1 pins. Refer to the LTM4601A
