MP4568
60V, 100mA Synchronous
Step-Down Converter
FEATURES
DESCRIPTION
The MP4568 is a high-frequency, step-down,
switching regulator with integrated highside/low-side, high-voltage power MOSFETs. It
provides a highly efficient output of up to
100mA.
60V rated MOSFETs and 4.5V to 45V operation
range accommodates a variety of step-down
applications in automotive input environment. A
5μA shutdown mode quiescent current allows
use in battery-powered applications.
It allows for high power conversion efficiency
over a wide load range by scaling down the
switching frequency under light-load condition
to reduce the switching and gate driver losses.
The switching frequency during start-up and
short circuit also can be scaled down to helps
prevent inductor current runaway. Thermal
shutdown provides reliable, fault-tolerant
operation.
The MP4568 is available in a 3mmx3mm
QFN10 package.

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.
3) The device is not guaranteed to function outside of its
operating conditions.

MP4568―60V, 100mA, SYNCHRONOUS STEP-DOWN CONVERTER
OPERATION
The MP4568 is a 60V, 100mA, synchronous,
step-down switching regulator with integrated
high-side and low-side high-voltage power
MOSFETs (HS_FET and LS_FET, respectively).
It provides a highly-efficient, 100mA output. It
features a wide input
voltage range,
internal/external soft-start control, and precision
current limit. Its very low operational quiescent
current makes it suitable for battery-powered
applications.
PWM Control
The ILIM comparator, FB comparator and zero
current detector (ZCD) block control the PWM. If
VFB is below the 1V reference and the inductor
current drops to zero, HS-FET turns on and the
ILIM comparator starts to sense the HS-FET
current: When the HS-FET current reaches the
limit set by the ILIM pin, or FB reaches the OVP
threshold, the HS-FET turns off and LS-FET
turns on together with the ZCD block. Meanwhile,
the ILIM comparator is turned off to reduce the
quiescent current. The LS-FET turns off together
with ZCD block after the inductor current drops to
zero. If VFB is less than the 1V reference at this
time, the HS-FET turns on at once and
commences another cycle. If VFB is still higher
than 1V reference, HS-FET would not turn on till
VFB drops below 1V.

Internal Regulator and BIAS
The 2.6V internal regulator powers most of the
internal circuitry. This regulator takes VIN and
operates in the full VIN range. When VIN is greater
than 3.0V, the output of the regulator is in full
regulation. Lower values of VIN result in lower
output voltages.
When VBIAS>2.9V, the BIAS supply overrides the
input voltage and supplies power to the 2.6V
internal regulator. When VBIAS>4.5V, it can power
LS driver furthermore. Using BIAS to power
internal regulator can improve the efficiency. It is
recommended to connect BIAS to the regulated
output voltage when it is in the range of 2.9V to
5.5V. When output voltage is out of above range,
an external supply that is >2.9V or even better
>4.5V is needed to power BIAS.
Enable Control
The MP4568 has a dedicated enable-control pin,
EN: when VIN goes high, the EN pin enables and
disables the chip. This is HIGH effective logic. Its
trailing threshold is 1.2V typically and its rising
threshold is about 400mV higher. When floating,
EN pin is internally pulled down to GND through
a 2M resistor to disable the chip.
When EN = 0V, the chip goes into the lowest
shutdown-current mode. When EN is higher than
zero but lower than its rising threshold, the chip
remains in a shutdown mode but with a slightly
larger shutdown current.
Internally a zener diode is connected from EN pin
to GND pin. The typical clamping voltage of the
zener diode is 7.5V. So VIN can be connected to
EN through a high ohm resistor if the system
doesn't have another logic input acting as enable
signal. The resistor needs to be designed to limit
the EN pin sink current less than 100μA. Just
note that there is an internal 2M resistor from EN
to GND, so the external pull up resistor should be
smaller than
[VIN(MIN) - 1.6V]  2M
1.6V
to make sure the
part can EN on at the lowest operation VIN.

MP4568―60V, 100mA, SYNCHRONOUS STEP-DOWN CONVERTER
Under-Voltage Lockout
VIN under voltage lockout (UVLO) protects the
chip from operating below the operational supply
voltage range. The UVLO-rising threshold is
about 4V while its trailing threshold is about 3.5V.
Soft-Start
Reference-type soft-start prevents the converter
output voltage from overshooting during startup.
When the chip starts, the internal circuitry
generates a constant current to charge external
SS capacitor. The soft-start (SS) voltage slowly
ramps up from 0V at a slow pace set by the softstart time. When VSS is less than the VREF, VSS
overrides VREF so the error amplifier uses VSS
instead of VREF as the reference. When VSS is
higher than VREF, VREF resumes control.
VSS is also associated with VFB. Though VSS can
be much smaller than VFB, it can only barely
exceed VFB. If somehow VFB drops, VSS tracks
VFB. This function aides in short-circuit recovery:
when a short-circuit is removed, the SS ramps up
as if it is a fresh soft-start process. This prevents
output voltage overshoot.
Thermal Shutdown
Thermal shutdown prevents the chip from
thermally running away. When the silicon die
temperature exceeds its upper threshold, the
thermal shutdown feature shuts down the whole
chip. When the temperature falls below its lower
threshold, the chip resumes function.
Floating Driver and Bootstrap Charging
The external bootstrap capacitor powers the
floating MOSFET driver. This floating driver has
its own UVLO protection, with a rising threshold
of about 2.4V with a hysteresis of about 300mV.
During this UVLO, the SS voltage of the
controller resets to zero. When the UVLO is
disabled, the controller follows the soft-start
process.
SW. The external circuit must have enough
voltage headroom to accommodate charging.
As long as VIN is sufficiently higher than SW, the
bootstrap capacitor can charge. When the power
MOSFET is ON, VIN is about equal to SW so the
bootstrap capacitor cannot charge. The best
charging period occurs when the external freewheeling diode is on so that VIN - VSW is at its
largest. When there is no current in the inductor,
VSW equals VOUT so the difference between VIN
and VOUT can charge the bootstrap capacitor.
Under higher duty cycle operating conditions, the
time period may not fully-charge the capacitor.
If the external circuit does not have sufficient
voltage and time to charge the bootstrap
capacitor, extra external circuitry can be used to
ensure the bootstrap voltage in normal operation
region.
Startup and Shutdown
If both VIN and VEN are higher than their
appropriate thresholds, the chip starts operating.
The reference block starts first, generating stable
reference voltage and currents, and then enables
the internal regulator. The regulator provides
stable supply for the rest device.
While the internal supply rail is high, an internal
timer holds the power MOSFET off for about
50µsec to blank startup glitches. When the
internal soft-start block is enabled, it first holds its
SS output low and then slowly ramps up.
Three events shut down the chip: VEN low, VIN
low, and junction temperature triggers the
thermal shutdown threshold. For shutdown, the
signaling path is blocked first to avoid any fault
triggering. Internal supply rail are pulled down
then. The floating driver is not subject to this
shutdown command, but its charging path is
disabled.
The dedicated internal bootstrap regulator
charges and regulates the bootstrap capacitor to
about 5V. When the voltage difference between
BST and SW falls below its working parameters,
a PMOS pass transistor connected from VIN to
BST turns on to charge the bootstrap capacitor.
The current path is from VIN to BST and then to

APPLICATION INFORMATION
Setting Peak Current
The peak current can be programmed from
55mA to 260mA by changing the resistor
between ILIM pin and ground. The peak current
setting resistor RILIM can be calculated by the
formula:
RILIM 
22
Ipeak
(k)
Where 55mA≤Ipeak≤260mA.
When RILIM≤84kΩ, Ipeak is clamped at its
maximum value 260mA; when RILIM≥400kΩ,
Ipeak is clamped to its minimum value 55mA. To
be convenient, ILIM pin can be just shorted to
GND when Ipeak is set at 260mA and floating
when Ipeak is set at 55mA.
When setting Ipeak, be noticed that the
maximum output current is equal to half of the
Ipeak. Make sure the Ipeak is high enough for
the output current requirement. Also be noticed
that higher Ipeak would result in higher inductor
current ripple, larger input and output voltage
ripple, which means bigger components (inductor,
input and output capacitors).
Selecting the Inductor
As the Ipeak is determined, for given input
voltage and output voltage, the inductor value
can be determined by the following formula:
L
keep the inductor working under control, the
inductor value should be chosen higher than
Lmin that is derived from below formula:
L MIN 
VIN(MAX )  TON(MIN)
Ipeak
Where VIN(MAX) is the max value of input voltage.
TON(MIN) is the designed 100ns minimum switch
on time.
Switching Frquency
Switching frequency can be estimated by below
equation.
fs 
2  Io  VOUT  VIN - VOUT 
2
Ipeak
 VIN  L
Higher Ipeak and inductor can get lower fs. And
fs inceases as Io increasing. When Io increases
to its maximal value Ipeak/2, fs also reaches its
highest value and can be derived by:
fs(max) 
VOUT  VIN - VOUT 
Ipeak  VIN  L
Below figures show the calculated fs(max) at
different VIN and inductor with typical Vo (3.3V
and 5V) and Ipeak (220mA).
VOUT  VIN - VOUT 
VIN  Ipeak  fs
Where fs is the switching frequency at the
maximal output current.
Larger inductor value results in lower switching
frequency, as well as higher efficiency. However,
the larger value inductor will have a larger
physical size, higher series resistance, and/or
lower saturation current as well as the slow load
transient dynamic performance. There is also a
lower limit of the inductor value, which is
determined by the minimum on time. In order to

Setting the Output Voltage
The output voltage is set using a resistive voltage
divider from the output voltage to FB pin. To get
the desired output voltage, divider resistor can be
chosen through below formula:
R1 VOUT

-1
R2 VREF
Where VREF is the FB reference voltage 1V.
The current flows into divider resistor would
increase the supply current, especially at no load

calculated from:

Under Voltage Lock Out Point Setting
MP4568 has internal fix under voltage lock out

while trailing threshold is about 3.5V. For the

be calculated by below formula.

recommended.

Soft Start Capacitor
There is an internal 1ms soft start when float SS
pin and this is the shortest soft start time. To get
longer soft start, it needs to add capacitor
between SS pin and GND. The soft start time is
the duration when SS is charged from 0 to FB
reference voltage 1V by an internal 3μA current
source. So the capacitor at SS pin can be chosen
according to below formula:

CSS  3  ΤSS (F)
PCB Layout
1) Keep the path of switching current short and
minimize the loop area formed by input
capacitor, high-side, low-side MOSFET and
output capacitor.
2) Bypass ceramic capacitors should be as
close as possible to the VIN pin.
3) Make sure that all feedback connections are
short and direct. Place the feedback resistors
as close to the chip as possible.
4) Keep SW away from sensitive analog areas
such as FB.
5) For better thermal performance and long-term
reliability consideration, VIN, SW and GND
should be connected to a large copper area
respectively to cool the chip.

Feedforward Capacitor
As described above that the PWM control
scheme of MP4568 is very special and the HS
turn on when FB drops lower than reference
voltage. This brings good load transient
performance. However, this also makes the HS
turn on moment is very sensitive to the FB
voltage. Once there is noise on FB, the moment
HS turns on is easy to be affected, and then Fsw
jitter would occur. The Fsw jitter is easy to
happen especially when Vo ripple is very small.
To improve the jitter performance, a small
feedforward capacitor between Vo and FB can
be used and typical 39pF is recommended.
