MPQ3410
1.3A, 550kHz Synchronous
Rectified Step-Up Converter
AEC-Q100 Qualified
The Future of Analog IC Technology
DESCRIPTION
FEATURES
The MPQ3410 is a highly efficient, synchronous,
fixed frequency, current-mode step-up converter
with output to input disconnect, inrush current
limiting and internal soft-start. It includes an error
amplifier, ramp generator, comparator, N-Channel
switch and P-Channel synchronous rectified
switch (which greatly improves efficiency). The
output disconnect feature allows the output to be
completely isolated from the input in shutdown
mode.
The 550kHz switching frequency allows for
smaller external components producing a
compact solution for a wide range of load currents.
The internal compensation and soft-start
minimizes the external component count and
limits the inrush current during startup. The
MPQ3410 has integrated power MOSFET which
can support up to 6V output and typical 1.3A
switch current.
The MPQ3410 is offered in a thin SOT23-5
package.

Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature TJ(MAX), the junction-toambient thermal resistance θJA, and the ambient temperature
TA. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by PD(MAX)=(TJ(MAX)TA)/θJA. Exceeding the maximum allowable power dissipation
will cause excessive die temperature, and the regulator will go
into thermal shutdown. Internal thermal shutdown circuitry
protects the device from permanent damage.
3) The device is not guaranteed to function outside of its
operating conditions.

MPQ3410 — 1.3A, 550kHz SYNCHRONOUS RECTIFIED STEP-UP CONVERTER, AEC-Q100 QUALIFIED
OPERATION
The MPQ3410 uses a 550kHz fixed-frequency,
current-mode regulation architecture to regulate
the output voltage. The MPQ3410 measures
the output voltage through an external resistive
voltage divider and compares that to the
internal 1.2V reference to generate the error
voltage. The current-mode regulator compares
the error voltage to the inductor current to
regulate the output voltage. The use of
current-mode regulation improves transient
response and control loop stability.
When the MPQ3410 is disabled (EN = Low),
both power switches are off. The body of the
P-Channel MOSFET connects to SW and there
is no current path from SW to OUT. Therefore,
the output voltage discharges to ground. When
the MPQ3410 is enabled (EN = High), the body
of the P-Channel MOSFET connects to OUT
and forms a forward diode from SW to OUT.
Thus the output voltage rises up toward the
input voltage. When output voltage crosses
1.6V the MPQ3410 starts the controller and
regulates the output voltage to the target value.
At the beginning of each cycle, the N-Channel
MOSFET switch is turned on, forcing the
inductor current to rise. The current at the
source of the switch is internally measured and
converted to a voltage by the current sense
amplifier. That voltage is compared to the error
voltage. When the inductor current rises
sufficiently, the PWM comparator turns off the
switch, forcing the inductor current to the output
capacitor through the internal P-Channel
MOSFET rectifier, which forces the inductor
current to decrease. The peak inductor current
is controlled by the error voltage, which in turn
is controlled by the output voltage. Thus the
output voltage controls the inductor current to
satisfy the load.
Soft-Start
The MPQ3410 includes a soft-start timer that
limits the voltage at the error amplifier output
during startup to prevent excessive current at
the input. This prevents premature termination
of the source voltage at startup due to inrush
current. This also limits the inductor current at
startup, forcing the input current to rise slowly to
the amount required to regulate the output
voltage during soft-start.

APPLICATION INFORMATION
COMPONENT SELECTION
Selecting the Inductor
Setting the Output Voltage
The inductor is required to force the output
voltage higher while being driven by the lower
input voltage. A good rule for determining the
inductance is to allow the peak-to-peak ripple
current to be approximately 30%-50% of the
maximum input current. Make sure that the
peak inductor current is below the minimum
current limit at the duty cycle used (to prevent
loss of regulation due to the current limit
variations).
Set the output voltage by selecting the resistive
voltage divider ratio. The voltage divider drops
the output voltage to the 1.19V feedback
voltage. Use a 100kΩ resistor for R2 of the
voltage divider. Determine the high-side resistor
R1 by the equation:
R1
VOUT VFB
VFB
R2
Where VOUT is the output voltage, VFB is the
1.19V feedback voltage and R2=100kΩ.
Selecting the Input Capacitor
An input capacitor is required to supply the AC
ripple current to the inductor, while limiting noise
at the input source. Multi-layer ceramic
capacitors are the best choice as they have
extremely low ESR and are available in small
footprints. Use an input capacitor value of 4.7μF
or greater. This capacitor must be placed
physically close to the device.
Selecting the Output Capacitor
A single 4.7µF to 10µF ceramic capacitor
usually provides sufficient output capacitance
for most applications. Larger values up to 22µF
may be used to obtain extremely low output
voltage ripple and improve transient response.
The impedance of the ceramic capacitor at the
switching frequency is dominated by the
capacitance, and so the output voltage ripple is
mostly independent of the ESR. The output
voltage ripple VRIPPLE is calculated as:
VRIPPLE
Calculate the required inductance value L using
the equations:
L
VIN (VOUT - VIN )
VOUT f SW I
IIN(MAX )
VOUT ILOAD (MAX )
VIN
I 30% 50%IIN(MAX )
Where ILOAD(MAX) is the maximum load current, ∆I
is the peak-to-peak inductor ripple current and η
is efficiency. For the MPQ3410, typically, 4.7µH is
recommended for most applications. Choose an
inductor that does not saturate at the peak
switch current as calculated above with
additional margin to cover heavy load transients
and extreme startup conditions.
ILOAD VO UT VIN
VO UT C2 f SW
Where VIN is the input voltage, ILOAD is the load
current, C2 is the capacitance of the output
capacitor and fSW is the 550kHz switching
frequency.

MPQ3410 — 1.3A, 550kHz SYNCHRONOUS RECTIFIED STEP-UP CONVERTER, AEC-Q100 QUALIFIED
Selecting the Feed-Forward Capacitor
LAYOUT CONSIDERATIONS
A feed-forward capacitor C3 in parallel with the
high-side resistor R1 can be added to improve
the output ripple at discontinuous conduction
mode and the load transient response (see
Figure 2). Up to 220pF for this capacitor is
recommended for 3.3V output applications.
High frequency switching regulators require
very careful layout for stable operation and low
noise. All components must be placed as close
to the IC as possible. All feedback components
must be kept close to the FB pin to prevent
noise injection on the FB pin trace. The ground
return of C1 and C2 should be tied close to the
GND pin. See the MPQ3410 demo board layout
for reference.
Selecting the Schottky Diode
A Schottky diode D1 in parallel with the highside P-Channel MOSFET is necessary to clamp
the SW node to a safe level for outputs of 4V or
above. A 0.5A, 20V Schottky diode can be used
for this purpose. See Figure 3.
