Description

LTM8027:

60V, 4A DC/DC

µModule® Regulator

Demonstration circuit 1307B features the LTM®8027

configured to deliver 12V from a 16V to 60V input. The

wide input range of the LTM8027 allows a variety of input

sources such as automotive batteries, wall adaptors and

industrial supplies. The LTM8027 is a step down converter,

so a minimum amount of headroom is required to keep

the output in regulation. A soft-start feature controls the

outputvoltageslewrateatstart-up,reducingcurrentsurges

andvoltageovershoots.Thecurrentmodecontrolscheme

creates fast transient response and good loop stability.
