DESCRIPTION
LTC3888-1
8-Phase, Dual-Output Synchronous Buck
Converter with Power System Management
Demonstration circuit 2652A-B is an 8-phase dual-output,
high efficiency, high density, synchronous buck converter
with 7V to 14V input range. Each output can supply up to
120A maximum load current with 1V output. The demo
board showcases the LTC
®
3888-1, which is a PMBus-
compliant dual loop 8-phase step-down DC/DC controller
with digital power system management. The LTC3888-1
is designed to work with DrMOS devices that provide an
output current sense and temperature monitor. Please
see LTC3888-1’s datasheet for more detailed information.
DC2652A-B powers up to default settings and produces
power based on configuration resistors (or with the set-
ting in its non-volatile memory) without the need for any
serial bus communication. This allows easy evaluation of All registered trademarks and trademarks are the property of their respective owners.

system management features of the part, download the
GUI software LTpowerPlay™onto your PC and use ADI’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.

QUICK START PROCEDURE
DC2652A-B is easy to set up to evaluate the performance
of the LTC3888-1. Refer to Figure2 for the proper mea-
surement equipment setup and follow the procedure
below.
1. With power off, connect the input power supply (7-14V)
to VIN (J1) and GND (J2).
2. Connect the 1.0V output load (Initial load:no load)
between VOUT0 (J3) and GND (J4).
3. Connect the 1.0V output load (Initial load:no load)
between VOUT1 (J5) and GND (J6).
4. Connect the DMMs to the input and outputs. Set default
jumper position:
JP1: ON
JP2: EXT
JP3: SLAVE
JP4: SLAVE
SW1: ON
SW2: ON
5. Turn on the input power supply and check for the
proper output voltages. VOUT0 should be 1.0V±0.5%
and VOUT1 should be 1.0V±0.5%.
6. Once the proper output voltages are established, adjust
the loads within the operating range and observe the
output voltage regulation, ripple voltage and other
parameters.
7. Connect the dongle and control the output voltages
from the GUI. See “LTpowerPlay Quick Start Procedure”
for details.
Note:
1. When measuring the efficiency, it is recommended to
monitor the VIN, VOUT0 and VOUT1 at the locations close
to the power stage. Here are examples:
(1) Monitor VIN across CIN9 and VOUT0 across
COUT11 for VOUT0 efficiency measurement
(2) Monitor VIN across CIN25 and VOUT1 across
COUT27 for VOUT1 efficiency measurement
2. When measuring the output or input voltage ripple, do
not use the long ground lead on the oscilloscope probe.
See Figure3 for the proper scope probe technique. Short,
stiff leads need to be soldered to the (+) and (–) terminals
of an output capacitor. The probe’s ground ring needs to
touch the (–) lead and the probe tip needs to touch the
(+) lead.
3. When doing the load transient test, it is recommended
to use a function generator to generate a pulse (~3%
duty cycle with 10~100Hz frequency). Then applying this
pulse to the EXT PULSE (E9) and GND (E10) turrets, the
dynamic load circuit will work well to achieve desired load
transient test by adjusting the amplitude, rising edge and
falling edge of the pulse.

LTPOWERPLAY SOFTWARE GUI
LTpowerPlay is a powerful Windows based development
environment that supports Analog Devices power system
management ICs and μModules, including LTM4675,
LTM4676, LTM4677, LTM4678, LTM4680, LTM4700,
LTC3880, LTC3882, LTC3883, LTC3884 and LTC3888-
1. The software supports a variety of different tasks. You
can use LTpowerPlay to evaluate Analog Devices ICs
by connecting to a demo board system. LTpowerPlay
can also be used in an offline mode (with no hardware
present) in order to build a multichip configuration file that
can be saved and reloaded at a later time. LTpowerPlay
provides unprecedented diagnostic and debug features. It
becomes a valuable diagnostic tool during board bring-up
to program or tweak the power management scheme in
a system, or to diagnose power issues when bringing
up rails. LTpowerPlay utilizes the DC1613A USB-to-I2C/
SMBus/PMBus controller to communicate with one of
many potential targets, including LTM4675, LTM4676,
LTM4677, LTM4678, LTM4680, LTM4700, LTC3880,
LTC3882, LTC3883, LTC3884 and LTC3888-1’s demo
system, or a customer board. The software also provides
an automatic update feature to keep the software current
with the latest set of device drivers and documentation.
The LTpowerPlay software can be downloaded from:

LTPOWERPLAY QUICK START PROCEDURE
The following procedure describes how to use LTpower-
Play to monitor and change the settings of LTC3888-1.
1.Download and install the LTpowerPlay GUI:
2. Launch the LTpowerPlay GUI.
a. The GUI should automatically identify the DC2652A-B.
The system tree on the left hand side should look like this:
b. A green message box shows for a few seconds in the
lower left hand corner, confirming that LTC3888-1 is
communicating:
c. In the Toolbar, click the R (RAM to PC) icon to read the
RAM from the LTC3888-1. This reads the configuration
from the RAM of LTC3888-1 and loads it into the GUI.
d. To change the output voltage to a different value, such
as 1.2V, enter 1.2 in the VOUT_COMMAND edit box,
as shown below:
Then, click the W (PC to RAM) icon to write these register
values to the LTC3888-1. After finishing this step, you will
see the output voltage will change to 1.2V.
If the write is successful, you will see the following mes-
sage:
e. You can save the changes into the NVM. In the tool bar,
click RAM to NVM button, as follows:
f. Save the demo board configuration to a (*.proj) file.
Click the Save icon and save the file.
