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 slewrate at start-up,reducing current surges

and voltage overshoots. The current mode control scheme

creates fast transient response and good loop stability.

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.

qUick stArt proceDUre

Demonstration circuit 1307B is an easy way to evaluate

the performance of the LTM8027. Refer to Figure 1 for

proper measurement equipment setup and follow the

procedure below:

1. Place JP1 on the ON position.

2. With power off, connect the input power supply to VIN

and GND. Preset the power supply within the input

voltage range.

3. Connect the load and preset to 0A.

4. Turn on the power at the input.

5. Check for the proper output voltage.

6. Once the proper output voltages are established, adjust

the loads within the operating range and observe the

output voltage regulation, ripple voltage, efﬁciency and

other parameters.
