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-to-
ambient 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.

OPERATION
Transformer Design
Figure 4: Isolated Flyback LED Driver
Figure 2: Simplified Flyback Converter
The MP4034 ensures that the circuit operates
in discontinues conduction mode (DCM). When
the IC internal MOSFET turns on, the current (iP)
flowing through transformer’s primary-side
winding (NP) increases linearly until it reaches
its peak current limit (IPK)
Startup
Initially, the IC is self-supplying through the
internal high-voltage current source, which is
drawn from the Drain pin. The internal high-
voltage current source will turn off for better
efficiency when VCC reaches the VCC ON
threshold. Then the transformer’s auxiliary
winding takes over as the power source. When
VCC falls below the VCC OFF threshold, the IC
stops switching and the internal high-voltage
current source turns on again. See Figure 3 for
the start-up waveform.

The relationship of peak current at ON period
and OFF period is:
This provides enough information to design the
transformer turn ratio.
Leading-Edge Blanking
NP
IPK _S
=
×IPK
Turning the power switch on induces a spike on
the sense resistor. To avoid falsely terminating
the switching pulse, the MP4034 includes a
300ns leading-edge blanking period. During this
blanking period, the current sense comparator
is disabled and the gate driver can not switch
off.
NS
Where NP is the number of primary winding
turns, and NS is the number of secondary
winding turns.
The MP4034 detects the secondary side diode
duty cycle by sampling the auxiliary winding
voltage and generates a ZCD signal as shown
in Figure 6.
DCM Detection
The MP4034 is designed to operate in
discontinuous conduction mode (DCM). To
avoid operating in continuous conduction mode
(CCM), the MP4034 detects the falling edge of
the FB input voltage with each cycle. If the chip
does not detect a 120mV falling edge, it will
stop switching.
Over Voltage Protection
The MP4034 has two levels of over-voltage
protection based on the FB voltage.
Figure 6: VFB and ZCD Waveforms
In normal operation, MP4034 samples the FB
pin voltage 3.5μs after the primary switch turns
off, as shown in Figure 6.
When the FB voltage is high—which means
that the current is flowing through secondary-
side diode—the ZCD signal goes high.
Conversely, when the FB voltage is low—which
means no current flows through the secondary-
side diode—the ZCD signal goes low, meaning
the secondary-side diode duty cycle (DS) is:
TS _ ON
DS =
TS _ ON + TS _ OFF

Then the average output current is:

When the MP4034 detects that the FB voltage

down immediately and discharge the VCC

Figure 8: LED String
Assume the forward voltage of one LED is VF
and the total number of LEDs on the string is N.
So the output voltage can be calculated as
N×VF. To ensure that OVP won’t trigger during
normal operation; the VFB should not exceed
VFBOVP1 (typical 4.0V). However, avoid a large
output voltage when OVP occurs. So the
voltage reflected on the FB pin should be:

Open-Circuit Protection (OCkP)
The MP4034 has open-circuit protection
(OCkP). If the −0.15V falling edge of VFB can
not be monitored—which means the feedback
loop is open—the MP4034 immediately shuts
off the driving signals and enters hiccup mode.
The MP4034 resumes normal operation when
the fault has been removed.
Thermal Shutdown (TSD)
When the temperature of the IC exceeds 150°C,
the over-temperature protection is enacted and
the IC enters auto-recovery mode. When the
temperature falls below 120°C, the IC resumes
working.

Use a Schottky diode because of its fast

better efficiency.
If a lower average efficiency (3%-4%) is
acceptable, replace the output diode with a PN-
junction diode or other non-Schottky diode to
lower costs.

The
Figure 9: Input Filter
transformer structure should be optimized to
improve the primary side and secondary side
coupling and minimize the transformer leakage
inductance of transformer. Aim for a leakage
inductance that is less than 5% inductance.
RCD Snubber
The transformer leakage inductance causes the
MOSFET drain voltage spike and the excessive
ringing on the drain voltage waveform.
The RCD snubber circuit can limit this Drain
voltage spike. Figure 11 shows the RCD snubber
circuit.
Figure 10: DC Input-Voltage Waveform
Bulk capacitors C1 and C2 filter the rectified AC.
Inductor L forms a π filter with C1 and C2 to
restrain the differential-mode EMI noise. The
resistor (R) in parallel with the inductor (L)
restrains the mid-frequency-band EMI noise.
Normally, R is selected between 1kΩ and 10kΩ.
The DC input capacitors, C1 and C2, are usually
2µF/W to 3µF/W for the universal input condition.
For a 230VAC single-range application, the
capacitor can be half that value. Normally, the
minimum DC voltage should not be too low to
ensure the converter can supply the maximum
power to the load which can be express as
follows:

Generally, a 15% ripple is reasonable. Use the
previous equation to approximate CSN.
For high or low temperature operation, select a
maximum switching frequency below 75kHz.
The damping resistor (R) in series with the RCD
has a relatively large value to prevent any
excessive ringing voltage that can affect the EMI.
Use a damping resistor of about 200Ω to 500Ω to
limit the drain voltage ringing.
Resistor Divider
For better application performance, use a resistor
divider with values in the range of 10kΩ to 100kΩ
to limit noise from adjacent components on the
FB pin. Connect a resistor with a value ranging
from 1kΩ to 2kΩ from the FB pin to the resistor
divider to limit substrate injection current effects,
as shown in Figure 12.

PCB Layout Guide
PCB layout is very important to achieve reliable
operation, and good EMI and thermal
performance. The use design guide as follows
to help optimize performance.
1. Minimize the loop area formed by the input
capacitor, the MP4034 drain-source, and the
primary winding to reduce EMI noise.
2. The copper area connected to source pins
acts as a heat sink. Provide a large copper area
to improve the thermal performance.
3. Minimize the clamp circuit loop to reduce EMI.
Bottom Layer
4. Minimize the secondary loop area of the
output diode and output filter to reduce the EMI
noise. In addition, provide a sufficient copper
area at the anode and cathode terminal of the
output diode for heat dissipation.
