DESCRIPTION
LTM4710-1
Low VIN, Quad 8A Silent Switcher
µModule Regulator
Demonstration circuit 3164A-B features the LTM
®
4710-1,
a quad DC/DC step-down µModule
®
regulator with 8A per
output, packaged in a compact (6mm × 12mm×3.54mm)
land grid array (LGA) with pre-made solder balls.
DC3164A-B has an operating input range of 2.5V to 5.5V.
The outputs of the four channels are 0.8V, 1.0V, 1.2V, and
1.5V with 8A per output, respectively. All outputs volt-
ages are programmable from 0.5V up to 3.6V (step-down
only). DC3164A-B operates by default at 1.5MHz and can
be adjusted by an external resistor from 1MHz to 5MHz or
by being synchronized to an external clock from 1.2MHz
to 2.6MHz. DC3164A-B also allows for the channels to be
paralleled up to 32A load current.

BOARD PHOTO
LTM4710-1 integrates four separate constant-frequency
peak current mode control regulators, power MOSFETs,
inductors, and other supporting discrete components.
It employs the second-generation Silent Switcher
®
technologyin which it allows fast switching edges for high
efficiency at high switching frequencies, while simulta-
neously achieving good EMI performance. Refer to the
LTM4710-1 data sheet for more detailed information.
It is recommended to read the data sheet of the LTM4710-1
prior to making any changes to the DC3164A-B board.
Design files for this circuit board are available.
Part marking is either ink mark or laser mark

Demonstration circuit 3164A-B is easy to set up to evalu-
ate the performance of the LTM4710-1. See Figure1 for
the proper measurement equipment setup and follow the
procedure below.
1. With power off, place the jumpers as shown in the
following positions.
NAME POSITION NAME POSITION
RUN1 ON MODE1 CCM
RUN2 ON MODE2 CCM
RUN3 ON MODE3 CCM
RUN4 ON MODE4 CCM
DAC ENABLE OFF
2. With power off, (see Figure1), connect the input
power supply between VIN and GND. Connect the out-
put loads between VOUT1 and GND, VOUT2 and GND,
VOUT3 and GND, and VOUT4 and GND, respectively.
3. Connect the DMMs to the input and outputs.
4. Turn on the input power supply.
NOTE: The input voltage should be between 2.5V
and5.5V.
5. Check for the proper output voltages. The output
voltage meters for each channel should display the
programmed output voltages (VOUT1 = 0.8V, VOUT2=
1.0V, VOUT3 = 1.2V, VOUT4 = 1.5V) within ±1.5%.
6. Once the input and output voltages are properly
established, adjust the load current within the operat-
ing range of 0A to 8A max for each channel. Observe
the output voltage regulation, output voltage ripples,
load transient response and other parameters.
7. Vary the input voltage from 2.5V to 5.5V. Observe the
output voltage regulation.
NOTE: When measuring the output or input voltage rip-
ple, do not use the long ground lead on the oscilloscope
probe. See Figure2 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.
OPTIONAL: An input EMI filter is included on the board.
To include this filter, connect the input supply positive
terminal to VEMI. Connect the input positive supply to
VIN to exclude the input EMI filter.

MULTIPHASE CONFIGURATION
For output loads that demand more than 8A of current,
multiple LTM4710-1 channels can be paralleled to run out
of phase to provide more output current without increas-
ing input and output voltage ripples. Figure3 shows the
typical paralleled application where channel 1 is used as
the main channel and the rest of LTM4710-1 channels
are programmed as the subordinary channels to achieve
the same switching frequency, interleaved phase shift and
current sharing among different channels.
The RT pin of the main phase is connected to a resistor
to AGND, programming the frequency and configuring
the MODE pin to become clock output used to drive the
MODE pin of the subordinary phase(s).
Connecting the FB pin to VIN configures a phase as a
subordinary phase. The MODE becomes an input, and the
voltage control loop is disabled. The subordinary phase
current control loop is still active, and the peak current
is controlled via the shared COMP node. The phase shift
of a subordinary phase relative to the main phase is pro-
grammed with a resistor divider on the RT pin. Refer to
the LTM4710-1 data sheet for more detailed information.
