operating as a multiphase 2MHz, 3V to 5.5V
input, 1.2V buck regulator. The DC3186A has three build
options to provide a two phase 25A, three phase 37.5A,
or four phase 50A output solution. The LTC3311 supports
adjustable output voltages from 0.5V to VIN and operat-

operation. All phases of DC3186A operate in forced con-
tinuous mode.
The DC3186A also has an EMI filter to reduce conducted
EMI. This EMI filter can be included by applying the input
voltage at the VIN EMI terminal. All registered trademarks and trademarks are the property of their respective owners.
PERFORMANCE SUMMARY
The Efficiency vs Load graph shows the efficiency of the
circuit with a 3.3V input for all three build options.
An on-board transient circuit is included to measure fast
transient performance.
The LTC3311 data sheet gives a complete description
of the part, its operation, and application information.
The data sheet must be read in conjunction with this
demo manual. The LTC3311 is assembled in a 3mm ×

setup and follow the procedure below:

and efficiency measure-
ments, measure VIN at the VIN SNSE and GND SNSN
turrets, and measure VOUT at the VOUT SNSE and GND
SNSE turrets, as illustrated as VM1 and VM2 in Figure1.
When measuring the input or output 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 output turrets or to TP1 as
shown in Figure2.
1. Set the JP1 Jumper to the HI position.
2. With power off, connect the input power supply to VIN
and GND. If the input EMI filter is desired, connect the
input power supply to VIN EMI and GND.
3. Set power supply PS1 current limit to 40A. Set the
electronic load LD1 to CC mode and 0A current. Slowly
increase PS1 to 1V. If PS1 output current reads less
than20mA,increasePS1to3.3V.VerifythatVM1reads
3.3V and VM2 reads 1.2V. Check VM1, VM2, VM3,
PS1 output current, and LD1 input current. Connect
an oscilloscope voltage probe as shown in Figure2.
Set Channel to AC-coupled, voltage scale to 20mV and
time base to 10µs. Check VOUT ripple voltage. Verify
that PGOOD voltage is above 3V.
4. Increase the load by 1A intervals up to full load and
observe the voltage output regulation, ripple voltage.
5. To test the transient response with a base load, add the
desired resistor to produce a minimum load between
VOUT and I_STEP turrets (RL shown on Figure1).
Note that the total load resistance will be RL plus
R16 (10mΩ). The DC3186A uses a buffered signal
generator input to drive a source follower circuit, and
to control the slew rate and amplitude of the current
transient. The source follower FET, Q1, operates in the
linear region during the load step.
6. Connect PS2 to DRIVER BIAS and GND turrets. Turn
on and set PS2 to 8V.
7. Set a signal generator with a 1ms pulse width, a 10ms
period and an amplitude from 0V to 4V, and then
connect it to SG_INPUT turret.
NOTE: Do not allow the pulse generator to have more
than a 20% duty cycle. This can allow too much power
to be dissipated in Q1 and can damage the FET.
8. Connect an oscilloscope with a time scale of 200µs/
div with one channel having a vertical scale of 2V/div
on the SG_INPUT and another with a vertical scale of
50mV/div to the I_STEP turret.
9. Measure the I_STEP voltage to observe the current,
VI_STEP/10mΩ. Adjust the amplitude of the pulse to
provide the desired transient. Adjust the rising and
falling edge of the pulse to provide the desired ramp
rate. Figure5 shows a load step from 10A to 20A in
1µs. Refer to the following equations:
I
OUT =
V
I_STEP
10mΩ
(1)
VGS = VSG_INPUT – VI_STEP (2)
10. When done, turn off SG1, PS1 and Load. Remove all
the connections to the demo board.

TYPICAL PERFORMANCE CHARACTERISTICS
THEORY OF OPERATION
Introduction to the DC3186A
The DC3186A demonstration circuit features the LTC3311,
an automotive grade low voltage synchronous step-down
Silent Switcher in a two, three, or four phase operation.
The LTC3311 is a monolithic, constant frequency, current
mode step-down DC/DC converter. Connecting the RT pin
of the master phase with a resistor to AGND programs
the frequency from 500kHz to 5MHz. With RTresistor
on master phase, the MODE/SYNC pin becomes a clock
output to drive the MODE/SYNC pins of the slave phases.
The DC3186A can operate with an external clock by short-
ing the master phase RT pin to VIN with a 0Ω resistor in
the R5 location and applying a clock signal on the MODE/
SYNC turret. If the EN pin is low, the LTC3311 is in shut-
down and in a low quiescent current state. When the EN
pin is above its threshold, the switching regulator will be
enabled.
Connecting the FB pin to VIN configures a phase as a
slave. The MODE/SYNC pin becomes an input, and the
voltage control loop is disabled. The current control loop
in the slave phase is still active, and the peak current
is controlled via the shared ITH node. The phasing of a
slave phase relative to the master phase is programmed
with a resistor divider on the RT pin. Refer to Table 5 of
the data sheet for more information on setting the slave
phase angle.
In the multiphase application, the LTC3311 operates in
forced continuous mode. At light loads, the slave phases
will continue to operate in forced continuous mode.
Setting the compensation for the multiphase is similar
to setting the compensation to the single phase. When
designing the compensation network, controlling the loop
stability and transient response are the two main con-
siderations. The LTC3311 has been designed to operate
at a high bandwidth for fast transient response capabili-
ties. This reduces output capacitance required to meet
the desired transient voltage range. The mid-band gain
of the loop increases with R8 and the bandwidth of the
loop increases with decreasing C14. C11 along with R6
provides a phase lead which will improve the phase mar-
gin. C13, C33, C34, and C44 along with R8 provides a
high frequency pole to reduce the high frequency gain.
C13, C33, C34, and C44 are in parallel on the ITH node.
The sum of these caps will be the total capacitance on the
master phase ITH pin. Too much capacitance will slow
down the response time.
Loop stability is generally measured using the Bode Plot
method of plotting loop gain in dB and phase shift in
degrees. The 0dB crossover frequency should be less
the 1/6 of the operating frequency to reduce the effects
of added phase shift of the modulator. The control loop
phase margin goal should be 45° or greater and a gain

The soft-start of the multiphase regulator is controlled by
a single cap, C12, on the master phase. After the regulator
is in regulation the SSTT pin can be used to monitor the
temperature of each IC. The master phase temperature
can be monitored at the SSTT turret and slave 1, 2, and 3
can be monitored at TP3, 4, and 6 respectively. Calculate
