600kHz fixed frequency PWM synchronous
step-down regulator. With a 3V to 6V bias
supply (VCC), MP2212 operates from a 3V to
16V input and generates an adjustable output
voltage from 0.8V to 0.9xVIN at up to 3A load

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

MP2212 – 16V, 3A, 600kHz SYNCHRONOUS STEP-DOWN CONVERTER
FUNCTIONAL DESCRIPTION
At this point the reference voltage takes over at
the non-inverting error amplifier input. The soft-
start time is internally set at 120µs. If the output of
the MP2212 is pre-biased to a certain voltage
during startup, the IC will disable the switching of
both high-side and low-side switches until the
voltage on the internal soft-start capacitor
exceeds the sensed output voltage at the FB pin.
PWM Control
The MP2212 is a constant frequency peak-
current-mode control PWM switching regulator.
Refer to the functional block diagram. The high
side N-Channel DMOS power switch turns on at
the beginning of each clock cycle. The current in
the inductor increases until the PWM current
comparator trips to turn off the high side DMOS
switch. The peak inductor current at which the
current comparator shuts off the high side power
switch is controlled by the COMP voltage at the
output of feedback error amplifier. The
transconductance from the COMP voltage to the
output current is set at 11.25A/V.
Over Current Protection
The MP2212 offers cycle-to-cycle current limiting
for both high-side and low-side switches. The
high-side current limit is relatively constant
regardless of duty cycles. When the output is
shorted to ground, causing the output voltage to
drop below 50% of its nominal output, the IC is
shut down momentarily and begins discharging
the soft start capacitor. It will restart with a full
soft-start when the soft-start capacitor is fully
discharged. This hiccup process is repeated until
the fault is removed.
This current-mode control greatly simplifies the
feedback compensation design by approximating
the switching converter as a single-pole system.
Only Type II compensation network is needed,
which is integrated into the MP2212. The internal
compensation in the MP2212 simplifies the
compensation
design,
minimizes
external
Bootstrap (BST PIN)
component counts. The loop bandwidth can be
adjusted by adding a feed-forward capacitor
which is in parallel with the feedback resistor from
output to FB pin.
The gate driver for the high-side N-channel
DMOS power switch is supplied by a bootstrap
capacitor connected between the BS and SW pins.
When the low-side switch is on, the capacitor is
charged through an internal boost diode. When
the high-side switch is on and the low-side switch
turns off, the voltage on the bootstrap capacitor is
boosted above the input voltage and the internal
bootstrap diode prevents the capacitor from
discharging.
Enable and Frequency Synchronization
(EN/SYNC PIN)
This is a dual function input pin. Forcing this pin
below 0.4V for longer than 4μs shuts down the
part; forcing this pin above 1.6V for longer than
4µs turns on the part. Applying a 500kHz to 2MHz
clock signal to this pin also synchronizes the
internal oscillator frequency to the external clock.
When the external clock is used, the part turns on
after detecting the first few clocks regardless of
duty cycles. If any ON or OFF period of the clock
is longer than 4µs, the signal will be intercepted
as an enable input and disables the
synchronization. For automatic startup, connect
this pin to VCC with a pull-up resistor. Don’t apply
a voltage more than VCC to this pin.
Input UVLO
Both VCC and IN pins have input UVLO detection.
Until both VCC and IN voltage exceed under
voltage lockout threshold, the parts remain in
shutdown condition. There are also under voltage
lockout hysesteres at both VCC and IN pins.
VCC Power Supply
VCC is the power supply of both the internal
control circuit and the gate drivers.
Soft-Start and Output Pre-Bias Startup
Generally, the VCC power supply could be
provided directly by a proper power rail or
generated from other VCC generation circuits. For
instance, Figure6 shows a typical VCC generation
circuit for VOUT=5V application.
When the soft-start period starts, an internal
current source begins charging an internal soft-
start capacitor. During soft-start, the voltage on
the soft-start capacitor is connected to the non-
inverting input of the error amplifier. The soft-start
period lasts until the voltage on the soft-start
capacitor exceeds the reference voltage of 0.8V.
It is noteworthy that the voltage applied on the
VCC pin should never be higher than 6V.

APPLICATION INFORMATION
is recommended for most applications. For best
efficiency, the inductor DC resistance shall be
<10mΩ. See Table 2 for recommended inductors
and manufacturers. For most designs, the
inductance value can be derived from the
following equation:
Setting the Output Voltage
The external resistor divider sets the output
voltage (see Figure 1). For typical applications,
choose R2 to be 10k Ω. R1 is then given by:

Feed-forward capacitor
Input Capacitor Selection
For applications with VOUT other than 0.8V,
adding a feed-forward capacitor in parallel with
the feedback resistor from output to FB pin can
increase loop bandwidth, help reducing transient
overshoot and undershoot and startup overshoot
if any. Figure 2 shows typical 5 VOUT application
circuit with a 390pF feed-forward capacitor.
The input capacitor reduces the surge current
drawn from the input and switching noise from
the device. The input capacitor impedance at the
switching frequency shall be less than input
source impedance to prevent high frequency
switching current passing to the input. Ceramic
capacitors with X5R or X7R dielectrics are highly
recommended because of their low ESR and
small temperature coefficients. For most
applications, a 47µF capacitor is sufficient.

MP2212 – 16V, 3A, 600kHz SYNCHRONOUS STEP-DOWN CONVERTER
PCB Layout Guide
Output Capacitor Selection
The output capacitor keeps output voltage ripple
small and ensures regulation loop stable. The
output capacitor impedance shall be low at the
switching frequency. Ceramic capacitors with
X5R or X7R dielectrics are recommended. If
electrolytic capacitor is used, pay attention to
output ripple voltage, extra heating, and the
selection of feedback resistor R1 (refer to “Output
Voltage Setting” section) due to large ESR of
electrolytic capacitor. The output ripple ∆VOUT is
approximately:
PCB layout is very important to achieve stable
operation. It is highly recommended to duplicate
EVB layout for optimum performance. If change
is necessary, please follow these guidelines as
follows. Here, the typical application circuit is
taken as an example to illustrate the key layout
rules should be followed.
1) For MP2212DQ, a PCB layout with more than
(or) four layers is recommended.
2) The high current paths (GND, IN and SW)
should be placed very close to the device with
short, direct and wide traces.
VOUTx(V − VOUT
)

IN
ΔVOUT
≤
x(ESR +
)
V xfOSCxL
8xfOSCxC3
IN
3) For MP2212DQ, two input ceramic capacitors
(2 x (10μF~22μF)) are strongly recommended to
be placed on both sides of the MP2212DQ
package and keep them as close as possible to
the “IN” and “GND” pins.
The output capacitance is recommended to be
less than 100μF.
External Schottky Diode
For this part, an external schottky diode is
recommended to be placed close to "SW" and
"GND" pins, especially when the output current is
larger than 2A.
For MP2212DN, an input ceramic capacitor
should be placed as close as possible to “IN” and
“GND” pins.
4) A RC low pass filter is recommended for VCC
supply. The VCC decoupling capacitor must be
placed as close as possible to “VCC” pin and
“GND” pin.
With the external schottky diode, the voltage
spike and negative kick on "SW" pin can be
minimized; moreover, the conversion efficiency
can also be improved a little.
5) The external feedback resistors shall be
placed next to the FB pin. Keep the FB trace as
short as possible.
For the external schottky diode selection, it's
noteworthy that the maximum reverse voltage
rating of the external diode should be larger than
the maximum input voltage. As for the current
rating of this diode, 0.5A rating should be
sufficient.
6) Keep the switching node SW short and away
from the feedback network.
