DESCRIPTION
LTC3315A
3.3V VIN, Dual 2A, 2MHz Buck Regulators at
1.2V and 1.8V Outputs in a 74mm2Solution
Demonstration Circuit DC3123A features the LTC©3315A
dual 5V, 2A Synchronous Step-Down DC/DC regulators
operating at 2MHz. One regulator provides a 1.2V output
and the other provides 1.8V, both up to a 2A load. The
LTC3315A supports adjustable output voltages from 0.5V
to VIN, operating frequencies from 1MHz up to 3MHz. The
LTC3315A is a compact, high efficiency, and high speed
synchronous monolithic step-down switching regulator.
Fast minimum on-time of 25ns enables high VIN to low
VOUT conversion at high frequency.
The DC3123A operating mode may be selected as Burst
Mode operation, Skip mode or Forced Continuous (FC)
mode. Setting JP1 to the FC/SYNC position will allow

PERFORMANCE SUMMARY
the LTC3315A to sync to a clock frequency from 1MHz
to 3MHz. The LTC3315A operates in Forced Continuous
mode when syncing to an external clock.
The LTC3315A data sheet gives a complete description
of the device, operation and application information. The
data sheet must be read in conjunction with this demo.
The LTC3315A is assembled in a 1.6mm × 1.6mm WLCSP
package.

QUICK START PROCEDURE
The DC3123A is easy to set up to evaluate the perfor-
mance of the LTC3315A. Refer to Figure1 and Figure2
for proper measurement equipment setup and follow the
evaluation procedure below.
NOTE:For accurate VIN, VOUT and efficiency measure-
ments, measure V
IN
at the V
IN
SNSE and GND SNSE turrets
and VOUT at the VOUT SNSE and GND SNSE turrets as illus-
trated as VM1, VM2 and VM3 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 JP2 and JP3 jumpers on the DC3123A board
to the HI position.
2. Set the JP1 jumper on the DC3123A board to the
desired position, BURST for best efficiency, FC/SYNC
for lowest ripple, and PS for a compromise between
the two.
3. With power off, connect 0V to 6V, 5A power supply,
PS1, between VIN and GND with a series ammeter and
a voltmeter as shown in Figure1.
4. Turn on and set the PS1 input power supply to 3.3V
and observe that VOUT1 regulates to 1.2V and VOUT2
regulates to 1.8V.
NOTE:Makesurethattheinputvoltagedoesnotexceed6V.
5. With power off, connect a 0A to 2A load to VOUT1 and
GND with a series ammeter and a voltmeter as shown
in Figure1.
6. Turn on LOAD1 and slowly increase from 0A to 2A
and observe the output voltage. The output ripple may
also be observed using an oscilloscope with the probe
connected as shown in Figure2.
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.
7. Set LOAD1 to 500mA.
8. With power off, connect a second 0A to 2A load to
VOUT2 and GND with a series ammeter and a voltmeter
as shown in Figure1.
9. Turn on LOAD2 and slowly increase the from 0A to 2A
and observe the output voltage. The output ripple may
also be observed using an oscilloscope with the probe
connected as shown in Figure2.
10. Momentarily short VOUT1 to ground with a clip lead
and observe that the voltage on PGOOD drops to 0V.
11. To change the operating frequency of the LTC3315A,
an external clock must be used. To do this set the JP1
jumperontheDC3123AboardtotheFC/SYNCposition.
12. Set a pulse generator to output a 0V to 3.3V pulse at
2MHz, 50% duty cycle and connect it to the MODE/
SYNC terminal and GND.
13. Changethefrequencyofthepulsegeneratorfrom2MHz
to 3MHz and observe how observe how the frequency
of SW1 follows the pulse generator.
14. Set LOAD1 greater than 1.0A. With an oscilloscope
probe on SW1, remove the pulse signal to the MODE/
SYNC terminal and observe how the switch frequency
settles from 3MHz back to 2MHz.
15. To test the transient response with a base load, turn
off LOADx (LOAD1 or LOAD2) and add the desired
resistortoproduceaminimumloadbetweenVOUTx and
RSNSx turrets (RL shown on Figure1). Note that the
total load resistance will be RL plus RSNSx (100mΩ).
16. Adjust a signal generator with a 10ms period, 10%
duty cycle and an amplitude from 1V to 2V to start.
Measure the RSNSx voltage to observe the current,
VRSNSx/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, the LTC3315A
DC3123A transient plots and Figure3.
17. IOUTx = VRSNSx/100mΩ
VRSNSx = VSGx − VGSx
Observe load transient effect on VOUTx
18. Refer to the LTC3315A data sheet for more details on
how the LTC3315A operates.
19. When done, turn off all loads, signal generator and
power supplies.

THEORY OF OPERATION
Introduction to the DC3123A
The DC3123A demonstration circuit features the
LTC3315A, a 5V Dual 2A Low voltage Synchronous Step-
Down regulator. The LTC3315A is a monolithic, constant
frequency, current mode step-down DC/DC converter.
An internal oscillator 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 LTC3315A is in shutdown and in a low quiescent
current state. When the EN pin is above its threshold, the
switching regulator will be enabled. Buck 1 and Buck 2
are 180° out of phase with each other.
The MODE/SYNC pin sets the switching mode to pulse
skip, forced continuous, or burst mode. If an external
1MHz to 3MHz clock is connected to the MODE/SYNC
turret while the JP1 is set to the FC/SYNC position, the
LTC3315A switching frequency will sync to the external
clock while operating in forced continuous mode. See
the LTC3315A 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 VOUT
to VIN and the available inductor values. The maximum
allowable operating frequency may be calculated using a
minimum Ton of 45ns in the formula below.
f
SWMAX =
V
OUT
V
INMAX •TonMIN
Select an operating switching frequency below fSWMAX.
The LTC3315A has a requirement that the magnitude of
the ripple current in the output inductor be greater than
0.6A peak to peak. This will determine the maximum
inductor value for the application.
Accurately Measuring Output Ripple of the LTC3315A
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

THEORY OF OPERATION
oscilloscope 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 C3 & C4. These pads can also be
used to solder a coax cable or other oscilloscope probe
connector if desired.
The DC3123A uses 3-terminal capacitors, C9 and C10,
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 output
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 without the 3-terminal capacitor populated in C9.
