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.

MP100 – OFFLINE INDUCTOR-LESS REGULATOR
OPERATION
MP100 employs a smart inductor-less regulator
design (patent pending) to charge the VD
capacitor (C1 in Figure 4) from the offline AC
input, and then to deliver the stored energy to the
load with a stable output voltage. When VIN is
less than its 35V threshold, VD can be charged
up by up to 1.8A input current. An internal LDO
regulates VOUT to 12V and can supply up to
10mA load when VIN is between 85VAC and
305VAC. The proprietary design allows the
universal AC input to efficiently power the IC
directly.
will continue until the output short condition
ceases.
Startup
During the startup, the internal switch connected
between VIN and VB turns on when the input
voltage is within its charging window (typically
below 35V), thus gradually charging the VD
voltage. The LDO will not resume with a softstart until the VD voltage reaches 15.3V.
Thermal Shutdown Protection
Accurate temperature protection prevents the
chip from operating at exceedingly high
temperatures. When the silicon die temperature
exceeds 160°C, the whole chip shuts down.
When the temperature falls below its lower
threshold of 140°C, the chip is enabled again.
Active Bleeder Circuit
The input voltage may not enter its charging
window during normal operation due to parasitic
capacitance from VIN to GND. An active bleeder
circuit is enabled to pull down the VIN voltage
whenever the VD voltage falls below 14V to
guarantee that the output gets enough energy
from the input ports. In addition, when the power
supply shuts down, the active bleeder circuit
discharges the energy stored in the parasitic
capacitor to ensure that the circuit can restart
easily.
Power-Good
The MP100 integrates a power-good circuit to
signal that the output meets the controller IC’s
requirements. It is an open drain structure and
requires a pull-up resistor to VOUT. During start
up, the VOUT voltage rises smoothly. When it
reaches 80% of its normal value, the power-good
signal goes high after a 200µs delay to indicate a
normal output.
Over-Current Protection
The VD and VOUT voltages will drop
simultaneously if the output current exceeds its
normal value. When the VD voltage falls to 6.8V,
the second stage LDO shuts down immediately.
Then the input voltage charges VD to 15.3V to
enable the LDO. Due to the output current limit
circuit, the maximum current is typically limited to
150mA.
VD Over-Voltage Protection
The VD capacitor provides energy for the output
load. If the voltage of VD exceeds 30V, the
internal switch between VIN and VB turns off
immediately to prevent the VD voltage from rising
too high, which can damage the LDO stage.
Short-Circuit Protection
The output current is limited to 150mA if the
output is shorted to ground, which also
decreases the VD voltage. When VD drops
below 6.8V, LDO turns off. The input voltage then
gradually charges VD up to 15.3V to enable the
LDO. When LDO turns on, the output current
drops the VD voltage to 6.8V again. This process

APPLICATION INFORMATION
COMPONENT SELECTION
τ s is 20ms for a half-wave rectifier, and 10ms for
The output voltage is set to 12V by internal large
feedback resistors. Adjust VOUT by choosing
appropriate external feedback resistors. The
recommended output voltage is between 1.5V
and 15V. If PG is used, then the maximum output
voltage must be limited to 14V due to the
maximum rating of PG. Defining the upper and
lower feedback resistors as RUP and RLW
respectively (refer to the picture in Typical
Application section):
RUP
VOUT
= RLW × (
− 1)
1.235
For the external resistors to dominate over the
internal resistors, select relatively small values of
RUP and RLW compared to the internal resistors.
However, to minimize the load consumption,
avoid very small external resistors. For most
applications, choose RLW=10.2kΩ. To accurately
set the output voltage, select an RUP that can
counter the internal upper-feedback resistor
value of 1MΩ. The table below lists typical
resistor values for different output voltages:

Selection of VD Capacitor
The bypass capacitor on the VD pin needs to be
sufficiently large to provide a stable current.
Calculate the capacitance (in μF) based on the
following equation:
CVD =
Iload × τs
Vripple
Where, Iload is the output current (mA); τ s is
based on the type of input rectifier—for example,
a full-bridge rectifier, Vripple is the voltage ripple on
the VD capacitor—normally the ripple is limited to
2V to 3V. For best results, use a small ceramic
capacitor and a large aluminum capacitor in
parallel.
Output Power Capability
The maximum input power to the VD capacitor is
limited by the fixed charging window. Considering
the LDO power loss, the MP100 has a limited
maximum output power.
The following factors influence the MP100’s
maximum output power: the input rectifier (full
bridge or half-wave); the VD capacitor connected
between VD and GND; the output voltage; and
the MP100’s temperature-rise requirement, which
is relative to the different application
environments.

MP100 – OFFLINE INDUCTOR-LESS REGULATOR
The maximum output capability can be roughly
estimated by following equation:
less than 10. R1 can be used to adjust the switch
speed of external MOS.
2 × C VD × Ipeak × fline × (VTHVIN − VDMIN ) × Vo
Line Transformer
MP100 can work well when connected to AC line
or programmable AC source. But when using an
isolation transformer or a variable transformer as
source, because of the high inductance of the
transformer (usually in the mH’s), high voltage
spikes occur when MP100 turns off the internal
switch connected between VIN and VB, which
may damage the IC. An X- capacitor must be
installed before the rectifier to guarantee the
reliability of the system.
Po _ max =
Ipeak + 2 × 2π × Cvd × Vin × fline
Where,
CVD ( F) is the capacitance connected to VD;
Ipeak (A) is the input peak current at full load,
which can be estimated by following equation:
Ipeak = 1.25 − 0.036 × VDMIN ;
fline (Hz) is the rectified line frequency;
VTHVIN (V) is the input voltage threshold to shut
down the internal switch connected between VIN
and VB, typically it is 35V;
VDMIN (V) is the minimum voltage of VD to
maintain the output voltage, usually; it can be got
by following equation:
⎧V + 1
VDMIN = ⎨ o
⎩ 6.8V
if VDMIN > 6.8V
if VDMIN ≤ 6.8V
Vo (V) is the output voltage;
Vin (V) is the RMS value of input voltage;
To get more output power, MP100 can be
paralleled. Figure 6 shows how it is implemented.
More MP100 can be paralleled in the same way
to get the output power need.
Another way to get more output power is using
an external MOSFET to charge the capacitor
connected between VD and GND. Figure 7
shows an example. To prevent the thermal
damage of external MOS when VD is shorted to
GND directly, PTC (Positive Temperature
Coefficient) is used which should be placed as
close as to the external MOS to detect the
temperature. When the temperature of external
MOS reaches certain value, the resistor of PTC
will increase sharply to pull down the gate
voltage and shut down the external MOS. To
guarantee its normal start up and steady state
operation, R3/R2 should be more than 4.5. At the
same time, R3/R2 should not be too high to get
better thermal protection; generally it should be

EMI
An appropriate X-capacitor should be connected
between the input ports to guarantee the circuit
can meet EMI requirements. Figure 3 shows the
recommended X-capacitor values to pass EMI in
different applications.

Surge
Since there is no capacitor to absorb AC line
transients, MOV should be used to protect the IC
to survive the transient test.
With 750V switch integrated, MP100 can pass
1kV surge test with an appropriate MOV
connected between the line input ports.
