DESCRIPTION
LTM8008: 72VIN,
6-Output DC/DC SEPIC
µModule Regulator
Demonstration circuit 1630A features the LTM
®
8008, a
72VIN μModule
®
SEPIC converter with six post regulators:
one 5V output at 500mA, one 3.3V output at 300mA, and
four 5V outputs at 150mA. The demonstration circuit is
designed to operate from a 3V to 72V input source and
the output of the SEPIC converter is internally set to 5.6V.

QUICK START PROCEDURE
Demonstration circuit 1630 is an easy way to evaluate the
performance of the LTM8008.
Referto Figure1 forproper measurementequipment setup
and follow the procedure below:
Note: When measuring the input or output voltage ripples,
care must be taken to avoid a long ground lead on the
oscilloscope probe. Measure the input or output voltage
ripples by touching the probe tip directly across the VIN
or VOUT and GND terminals. See Figure 2 for proper scope
probe technique.
1. Place JP1 on the ON position.
2. With power off, connect the input power supply to VIN
and GND.
3. Turn on the power at the input. The minimum VIN start
voltage is 6V. Once it starts, the converter can operate
down to 3V.
4. Check for the proper output voltages.
Note: If there is no output voltage, temporarily disconnect
the load to make sure that the load is not set too high.
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.
