MP2108
2A, 6V, 740KHz
Synchronous Buck Converter
The Future of Analog IC Technology
DESCRIPTION
FEATURES
The MP2108 is a 2A, 740KHz synchronous
buck converter designed for low voltage
applications requiring high efficiency. It is
capable of providing output voltages as low as
0.9V, and integrates top and bottom switches to
minimize power loss and component count. The
740KHz switching frequency allows for small
filtering components, further reducing the
solution size.

MP2108 – 2A, 6V, 740KHz SYNCHRONOUS BUCK CONVERTER
The MP2108 measures the output voltage
The average inductor current is controlled by

controlled by the output voltage. Thus the
output voltage controls the inductor current to
satisfy the load.
through an external resistive voltage divider and
compares it to the internal 0.9V reference to
generate the error voltage at COMP. The
current-mode regulator uses the voltage at
COMP and compares it to the inductor current
to regulate the output voltage. The use of
current-mode regulation improves transient
response and control loop stability.
Since the high-side N-Channel MOSFET
requires voltage above VIN to drive its gate, a
bootstrap capacitor from LX to BST is required
to drive the high-side MOSFET gate. When LX
is driven low (through the low-side MOSFET),
the BST capacitor is internally charged. The
voltage at BST is applied to the high-side
MOSFET gate to turn it on. Voltage is
maintained until the high-side MOSFET is
turned off and the low-side MOSFET is turned
on, and the cycle repeats. Connect a 10nF or
greater capacitor from BST to SW to drive the
high-side MOSFET gate.
At the beginning of each cycle, the high-side
N-Channel MOSFET is turned on, forcing the
inductor current to rise. The current at the drain
of the high-side MOSFET is internally
measured and converted to a voltage by the
current sense amplifier.
That voltage is compared to the error voltage at
COMP. When the inductor current rises
sufficiently, the PWM comparator turns off the
high-side switch and turns on the low-side
switch; forcing the inductor current to decrease.

Figure 2—Typical Application Circuit
Internal Low-Dropout Regulator
Soft-Start
The internal power to the MP2108 is supplied
from the input voltage (VIN) through an internal
2.4V low-dropout linear regulator, whose output
is VREF. Bypass VREF to SGND with a 10nF
or greater capacitor for proper operation. The
internal regulator can not supply more current
than is required to operate the MP2108.
Therefore, do not apply any external load to
VREF.
The MP2108 includes a soft-start timer that
slowly ramps the output voltage at startup to
prevent excessive current at the input.
When power is applied to the MP2108, and
RUN is asserted. A 2µA internal current source
charges the external capacitor at SS. As the
capacitor charges, the voltage at SS rises. The
MP2108 internally limits the feedback threshold
voltage at FB to that of the voltage at SS. This
forces the output voltage to rise at the same

type. All ceramic capacitors should be placed
close to the IC. For most applications, a 10µF
ceramic capacitor will work.
The soft-start period is determined by the
equation:
Selecting the Output Capacitor
The output capacitor (C2) is required to
maintain the DC output voltage. Low ESR
capacitors are preferred to keep the output
voltage ripple to a minimum. The characteristics
of the output capacitor also affect the stability of
the regulation control system. Ceramic,
tantalum, or low ESR electrolytic capacitors are
recommended.
tSS = 0.45 × C5
Where C5 (in nF) is the soft-start capacitor from
SS to GND, and tSS (in ms) is the soft-start
period. Determine the capacitor required for a
given soft-start period by the equation:
C5 = 2.22× tSS
The output voltage ripple is:
Use values for C5 between 10nF and 22nF to
set the soft-start period between 4ms and 10ms.

Setting the Output Voltage (see Figure 2)
Set the output voltage by selecting the resistive
voltage divider ratio. The voltage divider drops
the output voltage to the 0.9V feedback voltage.

voltage divider. Determine the high-side resistor

Where VRIPPLE is the output voltage ripple, fSW is
the switching frequency, VIN is the input voltage
and RESR is the equivalent series resistance of
the output capacitors.
Choose an output capacitor to satisfy the output
ripple requirements of the design. A 22µF
ceramic capacitor is suitable for most
applications.

Where R2 is the high-side resistor, R1 is the
low-side resistor and VOUT is the output voltage.
Selecting the Inductor
The inductor is required to supply constant
current to the output load while being driven by
the switched input voltage. A larger value
inductor results in less ripple current that in turn
results in lower output ripple voltage. However,
the larger value inductor is likely to have a
larger physical size and higher series
resistance. Choose an inductor that does not
saturate under the worst-case load conditions.
A good rule for determining the inductance is to
allow peak-to-peak ripple current to be
approximately 30% to 40% of the maximum
load current. Make sure that the peak inductor
current (the load current plus half the peak-to-
peak inductor ripple current) is below 2.5A to
prevent loss of regulation due to the current
limit.
Selecting the Input Capacitor
The input current to the step-down converter is
discontinuous, so a capacitor is required to
supply the AC current to the step-down
converter while maintaining the DC input
voltage. A low ESR capacitor is required to
keep the noise at the IC to a minimum. Ceramic
capacitors are preferred, but tantalum or low
ESR electrolytic capacitors are also an option.
The capacitor can be electrolytic, tantalum or
ceramic. Because it absorbs the input switching
current, it must have an adequate ripple current
rating. Use a capacitor with RMS current rating
greater than 1/2 of the DC load current.
For stable operation, place the input capacitor
as close to the IC as possible. A smaller high
quality 0.1µF ceramic capacitor may be placed
closer to the IC with the larger capacitor placed
further away.
If using this technique, it is recommended that
the larger capacitor be a tantalum or electrolytic

Calculate the required inductance value by the
equation:

VIN − VOUT

Where ∆I is the peak-to-peak inductor ripple
current. It is recommended to choose ∆I to be
30%~40% of the maximum load current.

The system crossover frequency (the frequency
where the loop gain drops to 1dB or 0dB) is
important. Set the crossover frequency below
one tenth of the switching frequency to insure
stable operation. Lower crossover frequencies
result in slower response and worse transient
load recovery. Higher crossover frequencies
degrade the phase and/or gain margins and
can result in instability.
Compensation
The system stability is controlled through the
COMP pin. COMP is the output of the internal
transconductance error amplifier. A series
capacitor-resistor combination sets a pole-zero
combination to control the characteristics of the
control system.
The DC loop gain is:

Determine if the second compensation
capacitor, C4 is required. It is required if the
ESR zero of the output capacitor happens at
less than half of the switching frequency or:
Figure 3—Add Optional External Bootstrap
Diode to Enhance Efficiency
The recommended external BST diode is
IN4148, and the BST cap is 0.1~1µF.
π × C2× RESR × fSW > 1
where RESR is the equivalent series resistance
of the output capacitor.
PCB Layout Guide
PCB layout is very important to achieve stable
operation. It is highly recommended to duplicate
EVB layout for optimum performance.
The second compensation capcacitor is
determined by the equation:
C2×RESR(max)
If change is necessary, please follow these
guidelines and take Figure 4 for reference.
C4 =
R3
Where RESR(MAX) is the maximum ESR of the
output capacitor.
1) Keep the path of switching current short
and minimize the loop area formed by Input
cap, high-side MOSFET and low-side
MOSFET.
2) Bypass ceramic capacitors are suggested
to be put close to the Vin Pin.
3) Ensure all feedback connections are short
and direct. Place the feedback resistors
and compensation components as close to
the chip as possible.
4) Route SW away from sensitive analog
areas such as FB.
5) Connect IN, SW, and especially GND
respectively to a large copper area to cool
the chip to improve thermal performance
and long-term reliability.
