DEMO MANUAL DC1590B
LTC3880: Dual Output
Step-Down DC/DC
Controller with Digital
Power Management
DESCRIPTION
Demonstration circuit 1590B is a dual output synchronous
buck converter featuring the LTC®3880EUJ, a dual output
peak current mode controller with digital power system
management. There are two versions of the board available:
• DC1590B-A: Senses the output current across a sense
resistor and has a default switching frequency of 350kHz.
• DC1590B-B: Senses output current with the inductor
DCR and has a default switching frequency of 425kHz.
Either version can be populated with the LTC3880EUJ-1,
instead of the LTC3880EUJ, which allows the user to provide bias power to the IC from an external power supply.
These boards provide two programmable outputs of 20A
each. The factory default settings are 1.8V for each output.
Both boards power up to default settings and produce power
based on configuration resistors without the need for any
serial bus communication. This allows easy evaluation of
the DC/DC converter. To fully explore the extensive digital

GUI software LTpowerPlay™ onto your PC and use LTC’s
I2C/SMBus/PMBus dongle DC1613A to connect to the
board. LTpowerPlay allows the user to reconfigure the part
on the fly and store the configuration in EEPROM, view
telemetry of voltage, current, temperature and fault status.

DEMO MANUAL DC1590B
QUICK START PROCEDURE
Demonstration circuit 1590B makes it easy to set up and
evaluate the performance of the LTC3880. Refer to Figure 3
for proper measurement equipment setup and follow the
procedure below:
Note: When measuring the input or output voltage ripple,
care must be taken to avoid a long ground lead on the
oscilloscope probe. Measure the output voltage ripple by
touching the probe tip directly across the C32 or C34. See
Figure 5 for proper scope probe technique.
1. Make sure jumpers are in the following positions:

JP4
OFF
EXTVCC_DRV—External VCC for LTC3880-1
JP5
NC
GPIO0B to GPIO1B—Tie GPIOs Together
2. With power off, connect the input power supply to VIN
and GND. Connect active loads to outputs.
3. Make sure both RUN switches are off.
4. Turn on the power at the input.
5. Turn on RUN switches as desired.
6. Check for the correct output voltages. VOUT1 = VOUT2
= 1.8V ± 0.5%
Note: If there is no output, temporarily disconnect the
load to make sure that the load current is not set too
high.
7. 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.
8. Connect the dongle and control the output voltages
from the GUI. See “LTpowerPlay GUI for the LTC3880
Quick Start Guide” for details.
Connecting a PC to DC1590B
You can use a PC to reconfigure the power management
features of the LTC3880 such as: nominal VOUT, margin
set points, OV/UV limits, temperature fault limits, sequencing parameters, the fault log, fault responses, GPIOs and
other functionality. The DC1613A dongle may be plugged
in regardless of whether or not VIN is present.
Note: Make sure that the input voltage does not exceed
24V.

QUICK START PROCEDURE
High Output Current Configuration
By default, the DC1590B powers up with two independently
adjustable outputs at 1.8V each. For >20A operation, it is
recommended to install the optional MOSFETs Q9 and
Q10 for large step-down ratios and Q7 and Q8 for small
step-down ratios.
Combining DC1590B with Other Digital Power Demo
Boards
The DC1590B may be plugged together in a multi-board
array with other digital power boards using optional J7
and J8.

QUICK START PROCEDURE
Measuring Efficiency (See Figure 4)
To accurately measure efficiency of any configuration, do
the following:
• Set JP3 to OFF to disable the regulator that provides
power to various auxiliary demo board components
like LEDs.
• Measure VIN across the input ceramic capacitor (C18,
C19). Measure VOUT across the output ceramic capacitor
(C24, C25).
To use the onboard LDO to drive INTVCC, make the following modifications to the demo board:
• Set JP4 to ON so that U7 provides the drive to EXTVCC.
U7 takes the place of the external power supply.
• Install R60.
To accurately measure efficiency of a demo board containing an LTC3880-1,
• Drive INTVCC from an external source through the pin
named: INTVCC/EXTVCC.
Evaluating the LTC3880-1
• Set JP4 to OFF to disable U7.
For applications that require the highest possible efficiency,
the LTC3880-1 allows the user to supply the bias voltage
and gate driver current from an external power supply.
Connect the power supply, 4.8V to 5.2V, to the EXTVCC
pin. Obtain a DC1590B with an LTC3880-1 installed from
your Linear Technology Field Applications Engineer.
• Measure VIN across the input ceramic capacitor (C18,
C19). Measure VOUT across the output ceramic capacitor
(C24, C25).
