PIN FUNCTIONS
Package
Pin #
Name Description
A resistor is connected from AAM pin to ground to set a AAM voltage force MP2314 into
non-synchronous mode when load is small. Drive AAM pin high (=VCC) or float AAM pin
will disable AAM mode and force MP2314 into CCM.

AAM
Supply Voltage. The MP2314 operates from a +4.5V to +24V input rail. C1 is needed to
decouple the input rail. Use wide PCB trace to make the connection.

Switch Output. Use wide PCB trace to make the connection.
System Ground. This pin is the reference ground of the regulated output voltage.
For this reason care must be taken in PCB layout. Suggested to be connected to GND with
copper and vias.

MP2314 – 24V, 2A SYNC STEP DOWN CONVERTER
OPERATION
The MP2314 is a high frequency synchronous
rectified step-down switch mode converter with
built in internal power MOSFETs. It offers a
very compact solution to achieve 2A continuous
output current over a wide input supply range
with excellent load and line regulation.
Under the light load condition, the value of
VCOMP is low. When VCOMP is less than VAAM and
VFB is less than VREF, VCOMP ramps up until it
exceeds VAAM. During this time, the internal
clock is blocked, thus the MP2314 skips some
pulses for PFM (Pulse Frequency Modulation)
mode and achieves the light load power save.
When MP2314 operates in fixed frequency
peak current control mode to regulate the
output voltage, the PWM cycle is initiated by the
internal clock. The integrated high-side power
MOSFET is turned on and remains on until its
current reaches the value set by the COMP
voltage. When the power switch is off, it
remains off until the next clock cycle starts. If, in
95% of one PWM period, the current in the
power MOSFET does not reach the COMP set
current value, the power MOSFET will be
forced to turn off.
Figure 2: Simplified AAM Control Logic
To enable AAM mode, connect a resistor from
AAM pin to GND. To disable AAM mode,
connect AAM to Vcc or float AAM pin the
converter will always operate in fixed frequency
CCM mode.
Internal Regulator
Most of the internal circuitries are powered from
the 5V internal regulator. This regulator takes
the VIN input and operates in the full VIN range.
When VIN is greater than 5.0V, the output of
the regulator is in full regulation. When VIN is
lower than 5.0V, the output decreases, a 0.1uF
ceramic capacitor for decoupling purpose is
required.
Enable/SYNC control
EN is a digital control pin that turns the
regulator on and off. Drive EN high to turn on
the regulator, drive it low to turn it off. There is
an internal 1MEG resistor from EN to GND thus
EN can be floated to shut down the chip. Also
EN pin voltage was clamped to around 6.5V by
an internal zener-diode. Please use large
enough pull up resistor connecting between VIN
and EN to limit the EN input current which
should be less than 100uA. Generally, around
100k resistor should be large enough for all the
applications.
Error Amplifier
The error amplifier compares the FB pin voltage
with the internal 0.791V reference (REF) and
outputs a COMP voltage, which is used to
control the power MOSFET current. The
optimized internal compensation network
minimizes the external component counts and
simplifies the control loop design.
The chip can be synchronized to external clock
range from 200kHz up to 2MHz through this pin
2ms right after output voltage is set, with the
internal clock rising edge synchronized to the
external clock rising edge. EN synchronize logic
high voltage should higher than 2V. EN
synchronize logic low voltage should lower than
400mV. EN logic high pulse width must less
than 1.6µs. Otherwise the internal clock may
come and turn on high side MOSFET again. EN
logic low pulse width must less than 6µs,
otherwise MP2314 may EN shutdown.
AAM Operation
The
MP2314
has
AAM
(Advanced
Asynchronous Modulation) power-save mode
for light load. Connect a resistor from AAM pin
to GND to set AAM voltage. Under the heavy
load condition, the VCOMP is higher than VAAM
.
When the clock goes high, the high-side power
MOSFET turns on and remains on until VILsense
reaches the value set by the COMP voltage.
The internal clock resets every time when VCOMP
is higher than VAAM
.

MP2314 – 24V, 2A SYNC STEP DOWN CONVERTER
Under-Voltage Lockout (UVLO)
Thermal shutdown is implemented to prevent
the chip from operating at exceedingly high
temperatures. When the silicon die temperature
is higher than 150°C, it shuts down the whole
chip. When the temperature is lower than its
lower threshold, typically 130°C, the chip is
enabled again.
Under-voltage lockout (UVLO) is implemented
to protect the chip from operating at insufficient
supply voltage. The MP2314 UVLO comparator
monitors the output voltage of the internal
regulator, VCC. The UVLO rising threshold is
about 3.9V while its falling threshold is
consistent 3.25V.
Floating Driver and Bootstrap Charging
The floating power MOSFET driver is powered
by an external bootstrap capacitor. This floating
driver has its own UVLO protection. This
UVLO’s rising threshold is 2.2V with a
hysteresis of 150mV. The bootstrap capacitor
voltage is regulated internally by VIN through
D1, R5, C5, L1 and C2 (Figure 3). If (VIN-VSW)
is more than 5V, U2 will regulate M3 to maintain
a 5V BST voltage across C5.
Pre-Bias Startup
The MP2314 has been designed for monotonic
startup into pre-biased loads. If the output is
pre-biased to a certain voltage during startup,
the BST voltage will be refreshed and charged.
If BST voltage exceeds its rising threshold
voltage and soft start voltage exceeds the
sensed output voltage at the FB pin, the part
starts to work normally.
Internal Soft-Start
The soft start is implemented to prevent the
converter output voltage from overshooting
during start up. When the chip starts, the
internal circuitry generates a soft-start voltage
(SS) ramping up from 0V. The soft-start period
lasts until the voltage on the soft-start capacitor
exceeds the reference voltage of 0.791V. At
this point the reference voltage takes over. The
soft-start time is internally set to be around
1.5ms.
Figure 3: Internal Bootstrap Charging Circuit
Startup and Shutdown
Over-Current-Protection and Hiccup
The MP2314 has cycle-by-cycle over current
limit when the inductor current peak value
exceeds the set current limit threshold.
Meanwhile, output voltage starts to drop until
FB is below the Under-Voltage (UV) threshold,
typically 50% below the reference. Once a UV
is triggered, the MP2314 enters hiccup mode to
periodically restart the part. This protection
mode is especially useful when the output is
dead-short to ground. The average short circuit
current is greatly reduced to alleviate the
thermal issue and to protect the regulator. The
MP2314 exits the hiccup mode once the over
current condition is removed.
If both VIN and EN are higher than their
appropriate thresholds, the chip starts. The
reference block starts first, generating stable
reference voltage and currents, and then the
internal regulator is enabled. The regulator
provides stable supply for the remaining
circuitries.
Three events can shut down the chip: EN low,
VIN low and thermal shutdown. In the shutdown
procedure, the signaling path is first blocked to
avoid any fault triggering. The COMP voltage
and the internal supply rail are then pulled down.
The floating driver is not subject to this
shutdown command.

inductor peak current is:
The external resistor divider is used to set the

FB
VOUT
The AAM voltage is used to setting the transition
point from AAM to CCM. It should be chosen to
provide the best combination of efficiency,
stability, ripple, and transient.
R2
Figure 4: T-type Network
If the AAM voltage is set lower, then stability and
ripple improves, but efficiency during AAM mode
and transient degrades. Likewise, if the AAM
voltage is set higher, then the efficiency during
AAM and transient improves, but stability and
ripple degrades. So the optimal balance point of
AAM voltage for good efficiency, stability, ripple
and transient should be found out.
Table 1 lists the recommended T-type resistors
value for common output voltages.

Selecting the Inductor
A 1µH to 10µH inductor with a DC current rating
of at least 25% percent higher than the maximum
load current is recommended for most
applications. For highest efficiency, the inductor
DC resistance should be less than 15mꢀ. For
most designs, the inductance value can be
derived from the following equation.

Selecting the Output Capacitor
The output capacitor (C2) is required to
maintain the DC output voltage. Ceramic,
tantalum, or low ESR electrolytic capacitors are
recommended. Low ESR capacitors are
preferred to keep the output voltage ripple low.
The output voltage ripple can be estimated by:

The input current to the step-down converter is
discontinuous, therefore a capacitor is required
to supply the AC current to the step-down
converter while maintaining the DC input
voltage. Use low ESR capacitors for the best
performance. Ceramic capacitors with X5R or
X7R dielectrics are highly recommended
because of their low ESR and small
temperature coefficients. For most applications,
a 22µF capacitor is sufficient.
Where L1 is the inductor value and RESR is the
equivalent series resistance (ESR) value of the
output capacitor.
In the case of ceramic capacitors, the
impedance at the switching frequency is
dominated by the capacitance. The output
voltage ripple is mainly caused by the
capacitance. For simplification, the output
voltage ripple can be estimated by:
Since the input capacitor (C1) absorbs the input
switching current it requires an adequate ripple
current rating. The RMS current in the input
capacitor can be estimated by:

The characteristics of the output capacitor also
affect the stability of the regulation system. The

capacitance and ESR values.

For simplification, choose the input capacitor
whose RMS current rating greater than half of
the maximum load current.
External Bootstrap Diode
The input capacitor can be electrolytic, tantalum
or ceramic. When using electrolytic or tantalum
capacitors, a small, high quality ceramic
capacitor, i.e. 0.1μF, should be placed as close
to the IC as possible. When using ceramic
capacitors, make sure that they have enough
capacitance to provide sufficient charge to
An external bootstrap diode may enhance the
efficiency of the regulator, the applicable
