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 

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.
