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
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.
