oper-
ating as a 6.6MHz, 3.3V to 1.8V 6A buck regulator. The
LTC3309B supports adjustable output voltages from
0.5V to VIN, and operating frequencies from 3MHz up to
10MHz. The LTC3309B is a compact, ultralow emission,
high efficiency, and high speed synchronous monolithic
step-down switching regulator. A minimum on-time of
22ns enables high VIN to low VOUT conversion ratios at
high switching frequencies.

operation, skip or forced continuous (FC)
mode. Setting JP1 to the FC/SYNC position will allow the
LTC3309B to sync to a clock frequency from 3MHz to
10MHz. The LTC3309B operates in forced continuous
mode when syncing to an external clock. The DC3054A-C
is set to a fixed 6.6MHz.
The DC3054A-C is set to a fixed 6.6MHz frequency by
connecting RT to VIN through a 0Ω resistor, R9. The fre-
quency can be easily changed by removing R9 and setting
an appropriate resistor in the R4 location to obtain the
desired frequency. Refer to the LTC3309B data sheet for
the proper RTvalue for a desired switching frequency.

PERFORMANCE SUMMARY
The DC3054A-C also has an EMI filter to reduce conducted
EMI. This EMI filter can be included by applying the input
voltage at the V
IN
EMI terminal. The EMI performance
of the board is shown in the EMI Test Results section.
The red lines in the EMI performance graphs illustrate
the CISPR25 Class 5 peak limits for the conducted and
radiated emission tests.
The LTC3309B data sheet gives a complete description
of the device, operation and application information. The
data sheet must be read in conjunction with this demo
manual. The LTC3309B is assembled in a 2mm × 2mm
LQFN package with exposed pads for low thermal resis-
tance. The layout recommendations for low EMI operation
and maximum thermal performance are available in the
data sheet section Low EMI PCB Layout.
The Efficiency vs Load graph shows the efficiency and
the power loss of the circuit with a 3.3V input in Burst
Mode operation.

QUICK START PROCEDURE
Demonstration circuit 3054A-C is easy to set up and use
to evaluate the performance of the LTC3309B. Refer to
Figure1 for proper measurement equipment setup and
follow the procedure below:
NOTE:For accurate V
IN
, V
OUT
and efficiency measure-
ments, measure VIN at the VIN SNSE and GND SNSE tur-
rets and V
OUT
at the V
OUT
SNSE and GND SNSE turrets as
illustrated as VM1 and VM2 in Figure1. When measuring
the input or output voltage ripple, care must be taken to
avoid a long ground lead on the oscilloscope probe.
1. Set the JP1 Jumper to the SKIP position and JP2 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.
3. Slowly increase PS1 to 1.0V. If AM1 reads less than
20mA, increase PS1 to 3.3V. Verify that VM1 reads
3.3V and VM2 reads 1.8V.
4. Connect an oscilloscope voltage probe as shown in
Figure2 in parallel with VM2. Set Channel to AC-cou-
pled, voltage scale to 20mV and time base to 100ns.
Observe the VOUT ripple voltage.
NOTE: Measure the output voltage ripple by touching the
probe tip directly across the output turrets or to TP1 as
shown in Figure2. TP1 is designed for a 50Ω coax cable
to reduce any high frequency noise that might couple into
the oscilloscope probes.
5. Verify that PGOOD turret is high.
6. Increasing the load by 1A intervals up to 6A and record
VM1, VM2, AM1 and AM2 for each interval.
7. Repeat step 6 for PS1 set to 2.5V and again for PS1
set to 5.0V.
8. Settheloadtoaconstant6A.Removetheoscilloscope
voltage probe from VOUT. Place a ground clip on PGND
terminal and set the voltage scale to 1V and the time
scale to 500ns/Division. Trigger on the rising edge of
the voltage probe. Using a tip on the voltage probe,
contact the SW node on the pad of L1. Observe the
duty cycle and the period of the switching waveform
(~152 nanoseconds).
9. Set the load current to 0.5A and repeat step 8. Observe
that the switching waveform is now operating in Pulse
Skip Mode.
10. Move the jumper on JP2 to LO. Verify that VOUT reads
0V and verify that PGOOD is low. Return jumper on
JP2 to HI and verify VM2 is 1.8V and verify PGOOD2
is high.
11. IfforcedcontinuousorBurstMode operation isdesired,
setPS1to 0V.MoveJP1to FC/SYNC orBURST.Repeat
steps 3 through 9. In step 9 observe that the switching
waveform is now operating in forced continuous or
Burst Mode operation.
12. To change the frequency, remove R9 if installed.
Install the desired RTresistor in the R4 location. Size
the inductor and output capacitors to provide the
desired inductor ripple and a stable output. Refer to
the LTC3309B data sheet and LTPowerCAD for more
information on choosing the required components.
13. To test the transient response with a base load, add
the desired resistor to produce a minimum load be-
tween VOUT and RSNS turrets (RL shown on Figure1).
Note that the total load resistance will be RL plus R11
(100mΩ).
14. Adjust a signal generator with a 10ms period, 10%
duty cycle and an amplitude from 1V to 2V to start.
15. Measure the RSNS voltage to observe the current,
VRSNS/100mΩ. 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. Refer to the following equations and the optional
transient response circuit shown in Figure3:
IOUT = VRSNS/100mΩ (2)
where
VRSNS = VSG_INPUT − VGS (3)
16. When done, turn off PS1 and Load. Remove all con-
nections to demo board.

THEORY OF OPERATION
Introduction to the DC3054A-C
The DC3054A-C demonstration circuit features the
LTC3309B, a low voltage synchronous step-down silent
switcher. The LTC3309B is a monolithic, constant fre-
quency, current mode step-down DC/DC converter. An
oscillator, with frequency set using a resistor on the RT
pin, turns on the internal top power switch at the beginning
of each clock cycle. Current in the inductor then increases
until the top switch comparator trips and turns off the
top power switch. If the EN pin is low, the LTC3309B is
in shutdown and in a low quiescent current state. When
the EN pin is above its threshold, the switching regulator
will be enabled.
The MODE/SYNC pin sets the switching mode to pulse
skip, forced continuous, or Burst Mode operation. If an
external 3MHz to 10MHz clock is connected to the MODE/
SYNC turret while the JP1 is set to the FC/SYNC position,
the LTC3309B switching frequency will sync to the exter-
nal clock while operating in forced continuous mode. See
the LTC3309B data sheet for more detailed information.
The maximum allowable operating frequency is influenced
by the minimum on time of the top switch, the ratio of
V
OUT
to V
IN
. The maximum allowable operating frequency
may be calculated using a minimum tON of 22ns in the
formula below.
fSW(MAX) =
V
OUT
V
IN(MAX) • tON(MIN)
Select an operating switching frequency below fSW(MAX).
The recommended ripple current in the output inductor is
1.8A peak-to-peak for the LTC3309B. This determines the
recommended inductor value for the application.
Accurately Measuring Output Ripple of the LTC3309B
With the fast edge rates of the circuit, high frequency
noise can be observed when measuring the output voltage
with 1MΩ terminated oscilloscope probes. To better view
the output ripple with oscilloscopes of 400MHz bandwidth
and above a 50Ω coax cable connected as close to the
output caps as possible should be used with the oscillo-
scope channel terminated to 50Ω at the scope. This will
help to reduce the noise coupling onto and displaying on
the scope. The demo board is set up to solder an U.FL,
RECEPT, ST SMD, 0Hz to 6GHz 50Ω connector (TP1) near
the output cap C4. These pads can also be used to sol-
der a coax cable or other oscilloscope probe connector
if desired.
The DC3054A-B uses 3-terminal capacitors, C18 and
C19, on the output to reduce the high frequency spikes
that can be observed with high bandwidth oscilloscopes.
The high frequency spikes are partially attributed to the
interwinding capacitance of the inductor and the voltage
step is partially attributed to the inductance in the out-
put capacitors. The step can be reduced by choosing low
ESL capacitors as close to the inductor as possible. The
high frequency spikes are reduced with using a small low
ESL 3-terminal capacitor with the self-resonant frequency
close to the high frequency spikes. Below is the output
ripple using a 500MHz scope, 50Ω probe measured at
TP1 on with the 3-terminal capacitor populated.
