DESCRIPTION
Demonstration circuit 1392A features the LTM
the high efficiency, high density switch mode step-down
μModule
to 5.5V with a jumper selectable output voltage from 0.8V
to 3.3V. The rated load current is 4A, while derating is
necessary for certain V
By using the TRACK pin, the output can be set to coin-
cidentally or ratiometrically track to another voltage rail.
