DESCRIPTION
LTC3888
8-Phase, Dual-Output Synchronous Buck
Converter with Power System Management
Demonstration circuit 2652A-A 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 LT C
®
3888, which is a PMBus-
compliant dual loop 8-phase step-down DC/DC controller
with digital power system management. The LTC3888 is
designed to work with DrMOS devices that provide an out-
put current sense and temperature monitor. Please refer
to LTC3888’s data sheet for more detailed information.
DC2652A-A 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

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-A is easy to set up to evaluate the performance
of LTC3888. Refer to Figure2 for the proper measurement
equipment setup and follow the procedure below.
1. With power off, connect the input power supply
(7V-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. ConnecttheDMMstotheinputandoutputs.Setdefault
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. Oncetheproperoutputvoltagesareestablished,adjustthe
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) MonitorVIN acrossCIN29 and VOUT1across COUT31
for VOUT1 efficiency measurement
2. When measuring the output or input voltage ripple,
do not use the long ground lead on the oscilloscope
probe. 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. Whendoing theloadtransienttest, itisrecommendedto
use a function generator to generate a pulse (~3% duty
cycle with 10Hz~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. Here are examples:
(1) Set the amplitude of the pulse to 3.4V for a 0A to 30A
load transient test with 10mΩ IOUT sensing resistor
(2) Set the amplitude of the pulse to 3.6V for a 0A to 40A
load transient test with 10mΩ IOUT sensing resistor

LTpowerPlay is a powerful Windows based development
environment that supports Analog Devices power sys-
tem management ICs and μModules, including LTM4675,
LTM4676, LTM4677, LTM4678, LTM4680, LTM4700,
LTC3880, LTC3882, LTC3883, LTC3884 and LTC3888.
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 pres-
ent) 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
LTPOWERPLAY SOFTWARE GUI
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’s demo sys-
tem, 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 LTpowerPlay
to monitor and change the settings of LTC3888.
1 Download and install the LTpowerPlay GUI:
here
2. Launch the LTpowerPlay GUI.
a. The GUI should automatically identify the DC2652A-A.
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 is
communicating:
c. In the Toolbar, click the “R” (RAM to PC) icon to read
theRAM fromtheLTC3888.This readstheconfiguration
from the RAM of LTC3888 and loads it into the GUI.
d. If you want to change the output voltage to a different
value, like 1.8V. In the Config tab, type in 1.8 in the
VOUT_COMMAND box, like this:
Then, click the “W” (PC to RAM) icon to write these
registervaluestotheLTC3888. After finishing this step,
you will see the output voltage will change to 1.8V.
If the write is successful, you will see the following
message:
e. You can save the changes into the NVM. In the tool
bar, click “RAM to NVM” button, as following
f. Save the demo board configuration to a (*.proj) file.
Click the Save icon and save the file. Name it whatever
you want.
