Description

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

output voltage slew rate at start-up, reducing current surges

and voltage overshoots. The current mode control scheme

creates fast transient response and good loop stability

The LTM8027 data sheet gives a complete description of

the part, operation and application information. The data

sheet must be read in conjunction with this manual before

working on or modifying demo circuit 1307B.
