The MP2102 is a dual-output, internally
compensated, 1.5MHz fixed frequency PWM
step-down converter. It is ideal for powering
portable equipment from a single cell Lithium-
Ion (Li+) Battery. Each channel of the MP2102
can supply 800mA of load current from a 2.5V
to 6V input voltage. Both output voltages can be
regulated as low as 0.6V.
The device features integrated high-side
switches and synchronous rectifiers for high
efficiency step-down conversion without the
need for external Schottky diodes. With peak
current mode control and internal compensation,
the MP2102 can be stabilized with ceramic
capacitors and small inductors. Fault condition
protection includes cycle-by-cycle current
limiting and thermal shutdown.
Available in 10-Pin QFN with Exposed Pad
and 10-Pin MSOP Packages.

MP2102 – 1.5MHz, 800mA DUAL-OUTPUT SYNCHRONOUS STEP-DOWN CONVERTER
OPERATION
The MP2102 is a dual-channel constant
frequency current mode PWM step-down
converter. The MP2102 is optimized for low
voltage, Li-Ion battery powered applications
where high efficiency and small size are critical.
Short Circuit Protection
The MP2102 has an independent short circuit
protection for each channel. When the output is
shorted to ground, the valley current limit
control is activated; the next cycle of turning on
the main switch will not start until the inductor
current has dropped to below 300mA. The
control mechanism will return to normal once
the feedback voltage reaches 0.3V.
The MP2102 uses an external resistor divider to
set the output voltage from 0.6V to 5.4V. The
device integrates both a main switch and a
synchronous rectifier which provides high
efficiency and eliminates the need for an
external Schottky diode.
Output Power Good Indication
The open-drain pin PWROK is used to monitor
the output condition. When the voltages of both
outputs are within ±10% of the expected value,
the open-drain device will turn off, floating the
PWROK pin. When at least one of the outputs
is outside of ±10% window, the PWROK will be
pulled “LOW”.
Current Mode PWM Control
Slope compensated current mode PWM control
provides stable switching and cycle-by-cycle
current limit for superior load and line response
and protection of the internal main switch and
synchronous rectifier.
Power-On Reset Delay
The MP2102 switches at a constant frequency
(1.5MHz) and regulates the output voltage.
During each cycle the PWM comparator
modulates the power transferred to the load by
changing the inductor peak current based on
the feedback error voltage. During normal
operation, the main switch is turned on for a
certain time to ramp the inductor current at
each rising edge of the internal oscillator, and
switched off when the peak inductor current is
above the error voltage.
The MP2102 has a programmable power on
reset delay. Changing the value of the capacitor
at the DLY pin sets the delay time. See
Programming
PWROK
Delay
in
the
Applications Information section.
Maximum Load Current
The MP2102 can operate down to 2.5V input
voltage; however the maximum load current
decreases at lower input due to large IR drop
on the main switch and synchronous rectifier.
When the main switch is off, the synchronous
rectifier will be turned on immediately and stay
on until the next cycle starts. The maximum
duty cycle of the MP2102 is around 90%,
therefore the maximum achievable output
voltage is 90% of the input voltage minus the
voltage drop across the main switch and the
inductor.
The slope compensation signal reduces the
peak inductor current as a function of the duty
cycle to prevent sub-harmonic oscillations at
duty cycles greater than 50%. Conversely, the
current limit increases as the duty cycle
decreases.

APPLICATION INFORMATION
Output Voltage Setting
Inductor Selection (L1, L2)
Please reference the schematic on the front
page. The external resistor divider sets the
output voltage. The top feedback resistor RTOP
also sets the feedback loop bandwidth with the
internal compensation capacitor (see Typical
Application circuit).
A 1µH to 10µH inductor with DC current rating
at least 25% higher than the maximum load
current is recommended for most applications.
For best efficiency, the inductor DC resistance
shall be <200mꢀ. See Table
2
for
recommended inductors and manufacturers.
For most designs, the inductance value can be
derived from the following equation:
Choose RTOP around 300kꢀ for optimal
transient response. The bottom feedback
resistor RBOT is then given by:
VOUT
×
(
VIN − VOUT
)
L =
VIN × ∆IL × fOSC
RTOP
RBOT
=
Where ∆IL is the inductor ripple current. Choose
inductor ripple current approximately 30% of the
maximum load current, 800mA.
VOUT
0.6V
− 1
Where RTOP is either R1 or R3, and RBOT is
either R2 or R4.
The maximum inductor peak current is:

Under light load conditions below 100mA, larger

efficiency. Table 3 lists inductors recommended
for this purpose.

MP2102 – 1.5MHz, 800mA DUAL-OUTPUT SYNCHRONOUS STEP-DOWN CONVERTER
Input Capacitor Selection (C1)
Thermal Dissipation
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 X7R or X5R dielectrics are
highly recommended because of their low ESR
and small temperature coefficients. For most
applications, a 4.7µF capacitor is sufficient.
Power dissipation shall be considered when
both channels of the MP2102 provide maximum
800mA output current to the loads at high
ambient temperature with low input supply
voltage. If the junction temperature rises above
150°C, the MP2102 two channels will be shut
down.
The junction-to-ambient thermal resistance of
the 10-pin QFN (3mm x 3mm) RΘJA is 50°C/W.
Therefore, the maximum power dissipation is
about 1.6W when the MP2102 is operating in a
70°C ambient temperature environment.
Output Capacitor Selection (C2, C3)
The output capacitor keeps output voltage
ripple small and ensures regulation loop
stability. The output capacitor impedance shall
be low at the switching frequency. Ceramic
capacitors with X5R or X7R dielectrics are
recommended. The output ripple ∆VOUT is
approximately:
150o C − 70o C
PDMAX
=
= 1.6W
50o C / W
PC Board Layout
The high current paths (GND, VIN and
SW1/SW2) should be placed very close to the
device with short, direct and wide traces. Input
capacitors should be placed as close as
possible to the VIN and GND pins. The external
feedback resistors shall be placed next to the
FB pins. Keep the switching nodes SW1/SW2
short and away from the feedback network.
