PIN FUNCTIONS
Pin #
Name
Description
Internal circuit supply pin. VCC is powered through the internal LDO from VIN. Connect a
capacitor from VCC to GND to bypass the internal regulator. The VCC capacitor must be at
minimum 1μF for flyback application and 4.7μF for forward application. VCC also can be
powered by an external power source to save internal LDO loss.
Current sense and frequency dither setting pin. See the Current Sense and Over-Current
Protection (OCP) section on page 14, as well as the Frequency Dithering section on page 14,
for more details.
Controller on/off control pin. The EN pin is internally connected to GND through a 2.5MΩ
resistor.

Dead time setting pin. The DT pin can configure the dead time between the GATE and
SYNC pins. A resistor below 33kΩ must be connected from DT to GND. See the Dead Time
Setting section on page 16 for more details.
Feedback pin through the optocoupler. COMP is internally pulled up to 5V through a 10kΩ
resistor.
Over-voltage monitor pin. When the voltage on the OV pin exceeds 2.5V, over-voltage
protection (OVP) is triggered. Connect OV to GND if OVP is not required.

Notes:
1) Exceeding these ratings may damage the device.
2) When the EN pull-up voltage is high, a current flows into the
EN pin. The current should be limited by an external pull-up
resistor. See the Enable Control Setting section on page 16
for more details.
3) OV is clamped by the internal circuit. The sink/source current
should be limited.
4) 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 P D
(MAX) = (TJ (MAX) - TA) / θJA. Exceeding the maximum
allowable power dissipation can cause excessive die
temperature, and the regulator may go into thermal shutdown.
Internal thermal shutdown circuitry protects the device from
permanent damage.
5) The device is not guaranteed to function outside of its
operating conditions.
6) Measured on EV6005A-Q-00A, 2-layer 90mmx35mm PCB.
7) The value of θJA given in this table is only valid for comparison
with other packages and cannot be used for design purposes.
These values were calculated in accordance with JESD51-7,
and simulated on a specified JEDEC board. They do not
represent the performance obtained in an actual application.

MP6005A – 420kHz, WIDE-INPUT FLYBACK AND FORWARD CONTROLLER
OPERATION
Start-Up and Power Supply
The MP6005A features an 80V internal start-up
circuit. When VIN exceeds 5.5V, the capacitor at
VCC is charged through the internal LDO.
Generally, VCC is regulated at 8.5V (if VIN is
sufficiently high), and the VCC under-voltage
lockout (UVLO) threshold is 5.7V. As well as
VCC UVLO, the MP6005A has an EN UVLO
threshold at 2V. When VCC is charged above its
5.7V UVLO threshold, and the EN pin is high,
the MP6005A begins working.
VCC can be powered from the transformer
auxiliary winding to save IC power loss after the
MP6005A starts switching. The auxiliary power
must exceed VCC regulation to override the
internal LDO. There is one internal reverse
blocking circuit, which means that VCC can
exceed VIN if VCC has biased power. VCC should
stay below 16V due to its voltage rating.
If VIN is below 8.5V and VCC cannot be
regulated to 8.5V, the internal, high-voltage
VCC LDO has a 1.5V voltage drop. This means
that the MP6005A can work when its input is as
low as 8V.
Enable Control
The EN pin enables and disables the
MP6005A. When the EN voltage exceeds 1V,
the MP6005A starts up some of the internal
circuits (micro-power mode). If the EN voltage
exceeds the turn-on threshold (2V), the
MP6005A enables all functions and starts the
GATE/SYNC driver signal. The GATE/SYNC
signal can be disabled when the EN voltage
drops to about 1.8V, but micro-power mode is
disabled only after the EN voltage falls below
0.4V. After shutdown, the MP6005A sinks a
maximum 1µA of current from the input power.
The EN pin can configure the VIN start-up
voltage through a resistor divider. The
maximum recommended voltage on the EN pin
is 6.5V. If the resistor divider voltage on EN
rises above 6.5V, the resistor divider should be
carefully considered to limit the current on the
EN pin. One internal Zener diode on EN clamps
the EN voltage when the resistor divider voltage
exceeds 6.5V. This ensures that the clamped
current flowing into EN is below 0.4mA with an
external pull-up resistor.
Pulse-Width Modulation (PWM) Operation
The MP6005A can be set to flyback and
forward topology. In flyback topology, the
external N-channel MOSFET turns on at the
beginning of each cycle and forces the current
in the transformer to increase. The current
through the MOSFET can be sensed. When the
sum of the SENSE current and slope
compensation signal rise above the voltage set
by the COMP pin, the external MOSFET turns
off. The transformer current then transmits
energy from the primary-side winding to the
secondary-side winding, and charges the output
capacitor through the Schottky diode.
The transformer’s primary-side current is
controlled by the COMP voltage (VCOMP). VCOMP
is then controlled by the output feedback
voltage through an external TL431 regulator
and the optocoupler. Therefore, the output
voltage controls the transformer current to
satisfy the load. In forward topology, the energy
is transferred from the primary-side to
secondary-side winding while the primary-side
N-channel MOSFET is on. The primary-side
peak current is also controlled by VCOMP.
Voltage Control
The output voltage (VOUT) feedback signal from
the optocoupler is amplified by secondary
circuitry, then directly fed back the signal to
COMP pin.
Under light-load conditions, the MP6005A
maintains a fixed frequency. The peak current
can drop when the COMP voltage decreases.
This current drop can trigger the power-save
mode (PSM) threshold.
Dead Time Setting
The DT pin can configure the dead time
between the GATE and SYNC pins. Table 1
lists the available configurations. The resistor
on the DT pin must be below 33kΩ.
After the MP6005A is enabled, there is a 500µs
period before the device starts switching. The
dead time and dither settings can be detected
by the MP6005A during this period.

The DT pin detection current lasts for about
200µs. Generally, it is sufficient to connect one
resistor from DT to GND. In noisy environments,
a capacitor can be placed between DT and
GND to provide filtering. It is recommended for
this capacitor to be below 100pF so that the DT
pin voltage can rise to a steady state before the
MP6005A detects the DT pin voltage. Do not
float the DT pin.
Frequency Dithering
The MP6005A integrates a frequency dithering
circuit to minimize EMI emissions. During
steady state, the frequency is fixed internally. A
frequency dithering circuit can be added to the
configured frequency with 1.5kHz modulation.
Frequency dithering can be configured to
±12.5kHz, ±25kHz, or ±37.5kHz by connecting
a resistor from the SENSE pin to GND (see
Table 2).

The SENSE pin detection current lasts for
about 200µs after start-up. Generally, it is
sufficient to connect one resistor to the SENSE
pin. In noisy environments, a capacitor can be
placed between SENSE and GND to provide
filtering.
Current Sense and Over-Current Protection
(OCP)
The MP6005A is a peak current mode
flyback/forward controller. The current through
the external MOSFET can be sensed through a
current-sense resistor that is connected in
series with the MOSFET’s source. The sensed
voltage on the SENSE pin is then amplified and
fed to the high-speed current comparator for
current mode control. The current comparator
takes this sensed voltage (plus slope
compensation) as one of its inputs, then
compares this value with VCOMP. When the
amplified current signal exceeds VCOMP, the
comparator outputs low, and the power
MOSFET turns off.
If the voltage on the SENSE pin exceeds the
current-limit threshold (about 160mV), the
MP6005A turns off the GATE output for the
cycle. The current is sensed again after the
internal oscillator starts the next cycle. The
MP6005A limits the MOSFET’s current cycle by
cycle.
Over-Voltage Protection (OVP)
The MP6005A provides over-voltage protection
(OVP). If the voltage on the OV pin exceeds
2.5V, the MP6005A shuts off the gate driving
signal and enters hiccup mode immediately.
The MP6005A restarts after 340ms and
resumes normal operation if the fault is
removed. Connect the OV pin to GND if OVP is
not required.
To avoid mistriggering due to the oscillation of
the leakage inductance and the parasitic
capacitance, there is an OVP blanking time.
Overload Protection (OLP)
The MP6005A limits the peak current cycle by
cycle during over-current (OC) conditions. If the
load continues increasing after triggering OCP,
the output voltage drops, and the peak current
triggers OCP every cycle.
The MP6005A sets the overload detection by
continuously monitoring the SENSE pin voltage.
Once internal soft start finishes, overload
protection (OLP) is enabled. If an OCP signal is
detected and lasts longer than 5ms, the
MP6005A turns off the GATE driver. After a
340ms delay, the MP6005A restarts with a new
start-up cycle.
During OLP, a 50µs one-shot timer is activated.
This timer also remains active for 50µs after
one OCP pulse. This means that if there is one
OCP pulse in a 50µs period, the MP6005A
registers OCP. If the OC condition is removed
within 4.95ms, the MP6005A resumes normal
operation.

MP6005A – 420kHz, WIDE-INPUT FLYBACK AND FORWARD CONTROLLER
Short-Circuit Protection (SCP)
When the output is shorted to the ground, the
part triggers over-current protection (OCP).
During OCP, the current is limited cycle by
cycle, and overload protection (OLP) may be
triggered as a result.
If the peak current cannot be limited by the
160mV SENSE voltage in every cycle due to
minimum gate on time, the current may run out
of control, and the transformer may saturate. If
the monitored SENSE voltage reaches 300mV,
the part turns off GATE and immediately runs in
hiccup mode with a 340ms off time.
If the short circuit is removed, the output
voltage recovers after the next restart cycle with
a 340ms delay.
Soft Start
The MP6005A provides soft start by charging
an internal capacitor with a current source.
During soft start, the SS signal controls COMP
and ramps up slowly. The soft-start capacitor is
discharged completely in the event of a
commanded shutdown, thermal shutdown, or
protection condition.
To avoid triggering short-circuit protection (SCP)
when the MP6005A starts up with a large
output capacitor, the MP6005A includes a
frequency soft-start function. The switching
frequency is controlled by the COMP voltage
(VCOMP). The frequency is about 100kHz when
VCOMP = 1.5V, and it linearly increases to
420kHz when VCOMP = 2.5V. Generally, it takes
about 20ms for VCOMP to ramp up from 1.5V to
3.5V. After soft start finishes, the soft start
function is disabled.
Minimum On Time
The transformer parasitic capacitance and gate
driver signal induce a current spike on the
sense resistor when the power switch turns on.
The MP6005A includes a 250ns leading edge
blanking period to avoid falsely terminating the
switching pulse. During this blanking period, the
current-sense comparator is disabled, and the
gate driver cannot switch off.
Gate Driver
The MP6005A integrates one high-current gate
driver for the primary-side N-channel MOSFET.
The high-current gate driver provides a strong
driving capability and benefits MOSFET
selection. If QG (the external MOFET’s total
gate charge) is low, then the switching speed
should remain low as well. It is recommended
to use a series resistance of 5Ω to reduce EMI.
The MP6005A also integrates one SYNC driver
pin. The SYNC pin turns the synchronous
switch off when SYNC is high, then turns the
synchronous switch on when SYNC is low.
Figure 2 shows the phase and dead time
relationship between GATE and SYNC.
If the MP6005A turns off due to under-voltage
lockout (UVLO) or a protection, both the GATE
and SYNC pins stay at a low voltage.

Over-Temperature Protection (OTP)
Thermal shutdown is implemented to prevent
the chip from thermal runaway. When the
silicon die temperature exceeds its upper
threshold, the MP6005A shuts down the whole
chip. When the temperature drops below the
lower threshold, thermal shutdown is removed,
and the chip is enabled again with a new start
cycle.

APPLICATION INFORMATION
Output Voltage Setting
The output voltage is set by an external TL431
regulator. If the TL431’s reference voltage is
2.5V, and expected output voltage is 12V, then
the upper and lower resistor divider ratio should
be 3.8. Then TL431 generates an amplified
signal that controls the MP6005A’s COMP pin
through an optocoupler, such as the PC357.
COMP controls the current, which regulates
VOUT using a feedback signal.

In flyback mode, the auxiliary winding supply

on the EN pin clamps the EN voltage when the

Zener diode clamps the current flowing into EN

The VCC voltage is regulated by the internal
LDO from VIN. Generally, VCC is regulated at
8.5V. It is recommended to place a decoupling

the MP6005A determines the frequency
dithering value (see Table 2 on page 14).

MP6005A – 420kHz, WIDE-INPUT FLYBACK AND FORWARD CONTROLLER
Current-Sense Resistor Setting
The MP6005A is a peak current mode
flyback/forward controller. The current through
the external MOSFET can be sensed through a
current-sense resistor. If the voltage sensed on
the SENSE pin exceeds the current-limit
threshold voltage (about 160mV), the MP6005A
turns off the GATE output for that cycle.
The on resistance of the MOSFET determines
the conduction loss. To reduce conduction loss,
the on resistance should be as low as possible.
To avoid reaching the current limit, the voltage
across the current-sense resistor (RSENSE)
should be below 80% of the current limit voltage
(about 160mV). RSENSE can be calculated with
Equation (3):
Consider the turn-on threshold voltage (VTH).
GATE is powered by VCC, so VTH must be
below VCC.
RSENSE
0.8 160mV
IPEAK
(3)
Where IPEAK is the primary-side peak current.
Selecting the Power MOSFET
The MP6005A is capable of driving a wide
variety of N-channel power MOSFETS. The
critical parameters for selecting a MOSFET are
the maximum drain-to-source voltage (VDS(MAX)),
maximum current (ID(MAX)), on resistance
(RDS(ON)), total gate charge (QG), and the turn-on
threshold (VTH).
In flyback mode, the off-state voltage (VMOSFET)
across the MOSFET can be calculated with
Equation (4):
VMOSFET VIN N VOUT
(4)
Where N is the transformer primary winding to
output winding ratio.
Consider the voltage spike when the power
MOSFET turns off. VDS(MAX) should be greater
than 1.5 times VMOSFET.
In forward mode, VMOSFET can be estimated with
Equation (5):
VMOSFET
D VIN
VIN
1 D
(5)
Where D is the duty cycle. The maximum duty
cycle is typically limited at 70%.
The current through the power MOSFET is at
its maximum when the input voltage is at its
minimum and the output power is at its
maximum. The current rating of the MOSFET
should be greater than 1.5 x IRMS.
QG is vital for MOSFET selection since it
determines the commutation time. A high QG
leads to high switching loss, while a low QG
may cause fast turn-on/off speeds. The turnon/off speeds determine the spike and kick.
Selecting the Transformer for Flyback Mode
In flyback mode, a transformer determines the
duty cycle, peak current, efficiency, MOSFET,
and output diode rating. A good transformer
should consider the winding ratio, primary-side
inductance,
saturation
current,
leakage
inductance, current rating, and core selection.
The transformer winding ratio determines the
duty cycle (D). Calculate D with Equation (6):
D
N VOUT
N VOUT VIN
(6)
Where N is the transformer primary winding to
output winding ratio. Typically, a duty cycle of
about 45% is recommended for most
applications.
The primary-side inductance affects the input
current ripple ratio factor. A higher inductance
results in a physically large transformer and
higher costs. A lower inductance results in a
high switching peak current and RMS current,
which reduces efficiency. Choose a primaryside inductance that makes the current ripple
ratio factor about 30% to 50%. Estimate the
primary-side inductance with Equation (7):
LP
VIN D2
2 n IIN fSW
(7)
Where n is the current ripple ratio, IIN is the
input current, and LP is the primary inductance.
Calculate LP based on the minimum input
voltage condition.
The transformer should have a high saturation
current to support the switching peak current.

Otherwise,
the
transformer
inductance
decreases sharply. The SENSE resistor can
limit the switching peak current. The energy
stored in the leakage inductance cannot couple
to the secondary side, which may a high spike
when the MOSFET turns off. This reduces
efficiency and increases MOSFET stress.
Normally, the transformer leakage inductance
can be controlled below 2% of the transformer
inductance.
The current rating uses the maximum RMS
current (IRMS), which allows current to flow
through each winding. The current density
should be controlled, as an unregulated current
can cause a high resistive power loss.
Selecting the RCD Snubber for Flyback
Mode
The transformer leakage inductance causes
spikes and excessive ringing on the MOSFET
drain voltage waveform, and the RCD snubber
circuit limits the MOSFET voltage spike (see
Figure 6).

Selecting the Output Diode for Flyback
Mode
The flyback output rectifier diode supplies
current to the output capacitor when the
primary-side MOSFET is off. Use a Schottky
diode to reduce losses from the diode forward
voltage and recovery time. The diode should be
rated for a reverse voltage 1.5 times greater
than VDIODE. VDIODE can be calculated with
Equation (11):
VDIODE
VIN

N
(11)
Where N is the transformer primary winding to
output winding ratio.
The average current rating must exceed the
maximum expected load current, and the peak
current rating must exceed the output winding
peak current. It is recommended to use an RC
snubber circuit for the output diode.
The transformer winding ratio determines the
duty cycle (D). D can be estimated with
Equation (12):

Selecting the Transformer for Forward Mode

When the power MOSFET turns on, the
transformer transfers energy to the output,
while VIN generates a primary-side inductance
current in the transformer. There must be
enough primary winding to prevent the
transformer from saturating.

The peak exciting current can be calculated
with Equation (13):
IEXC

Where IEXC is the primary-side inductance peak
current, and LP is the primary inductance. Use
IEXC to calculate the primary winding. Certain
margins are required for extreme conditions,
such as load transient and over-current
protection (OCP).
The current rating counts on the maximum
RMS current, which flows through each
winding. The current density should be
controlled. An unregulated current density can
cause a high resistive power loss.
Selecting the SYNC MOSFET for Forward
Mode
The MP6005A supports active-clamp forward
mode. The active clamp P-channel MOSFET
must have the same maximum voltage as the
main switch power MOSFET. The P-channel
MOSFET’s maximum current should exceed
the primary-side inductance peak current and
RMS current.
Selecting the Output MOSFET for Forward
Mode
The forward mode output uses two diodes to
conduct the current. If higher efficiency is
required, the diodes can be replaced with
MOSFETs (QF and QR) (see Figure 7).

The QF maximum VDS voltage (VF) can be

Equation (16):

The QF RMS current (IF) can be calculated with
Equation (17):

(

3 IOUT
(17)
The QR MOSFET’s gate driving voltage is equal
to VF, and the QF MOSFET’s gate driving
voltage is equal to VR. If the driving voltage
exceeds the MOSFETs’ maximum gate voltage,
a clamp circuit is required.
The MOSFET’s on resistance determines the
conduction loss, while QG determines the driver
circuit loss. Both the MOSFET’s on resistance
and QG should be low enough to obtain higher
efficiency and a lower rising temperature.
Selecting the Output Inductor for Forward
Mode
The forward mode output inductor must supply
constant current to the output load while the
main power MOSFET turns on. A larger-value
inductor results in less ripple current and a
lower output ripple voltage. However, a largervalue inductor has a larger physical size, higher
series resistance, and lower saturation current.
A good rule to determine the inductance is to
allow the peak-to-peak ripple current in the
inductor to be approximately 30% to 50% of the
maximum output current. The inductance value
(L) can be calculated with Equation (18):

Where VOUT is the output voltage, VIN is the
input voltage, fSW is the switching frequency,
and ΔIL is the peak-to-peak inductor ripple
current.
Choose an inductor that does not saturate
under the maximum inductor peak current.
Selecting the Input Capacitor
An input capacitor is required to supply the AC
ripple current to the inductor while limiting noise
at the input source. A low-ESR capacitor is
required to keep the noise near the IC at a
minimum.
Ceramic
capacitors
are
recommended, but tantalum or low-ESR
electrolytic capacitors are sufficient. For
ceramic capacitors, the capacitance dominates
the input voltage ripple at the switching
frequency.
In flyback mode, the input ripple can be
estimated with Equation (19):

the output voltage ripple. For ceramic
capacitors, the capacitance dominates the
output ripple at the switching frequency.

PCB Layout Guidelines
Efficient layout of the high-frequency switching

Poor layout may result in reduced performance,
excessive EMI, resistive loss, and system
