Dual 1.5MHz, 600mA Synchronous Step-Down Converter
FeaturesGeneral Description
Applications
•TV Tuner/Box
•Portable Instrument
The APW7134 contains two independent 1.5MHz con-
stant frequency, current mode, and PWM step-down
converters. Each converter integrates a main switch and
a synchronous rectifier for high efficiency without an ex-
ternal Schottky diode. The APW7134 is ideal for powering
portable equipment that runs from a single cell Lithium-
Ion (Li+) battery. Each converter can supply 600mA of load
current from a 2.5V to 5.5V input voltage. The output volt-
age can be regulated as low as 0.6V. The APW7134 can
also run at 100% duty cycle for low dropout applications.

Function Description
The APW7134 has dual independent constant frequency
current mode PWM step-down converters. All the main
and synchronous switches are internal to reduce the ex-
ternal components. During normal operation, the inter-
nal PMOSFET is turned on, however, it is turned off when
the inductor current at the input of ICOMP to reset the RS
latch. When the load current increases, it causes a slight
to decrease in the feedback voltage, which in turn, it
causes the EA’s output voltage to increase until the aver-
age inductor current matches the new load current. While
the internal power PMOSFET is off, the internal power
NMOSFET is turned on until the inductor current starts to
reverse, as indicated by the current reversal comparator
IRCMP, or the beginning of next cycle. When the NMOSFET
is turned off by IRCMP, it operates in the discontinuous
conduction mode.
Pulse Skipping Mode Operation
At light load with a relative small inductance, the inductor
current may reach zero. The internal power NMOSFET is
turned off by the current reversal comparator, IRCMP, and
the switching voltage will ring. This is discontinuous mode
operation and normal behavior for the switching regulator.
At very light load, the APW7134 will automatically skip
some pulses in the pulse skipping mode to maintain the
output regulation. The skipping process modulates
smoothly depend on the load.
Short Circuit Protection
In the short circuit situation, the output voltage is almost
zero volts. Output current is limited by the ICOMP to prevent
the damage of electrical circuit. In the normal operation,
the two straight lines of the inductor current ripple have
the same height, it means the volts-seconds product is
the same. When the short circuit operation occurs, the
output voltage down to zero leads to the voltage across
the inductor maximum in the on period and the voltage
across the inductor minimum in the off period. In order to
maintain the volts-seconds balance, the off-time must be
extended to prevent the inductor current run away. Fre-
quency decay will extend the switching period to provide
more times to the off-period, and then the inductor cur-
Dropout Operation
An important detail to remember is that on resistance of
PMOSFET switch will increase at low input supply voltage.
Therefore, the user should calculate the power dissipa-
tion when the APW7134 is used at 100% duty cycle with
low input voltage.
Slope Compensation
Slope compensation provides stability in constant fre-
quency current mode architecture by preventing sub-har-
monic oscillations at high duty cycle. It is accomplished
internally by adding a compensating ramp to the inductor
current signal at duty cycle in excess of 40%. Normally,
this results in a reduction of maximum inductor peak cur-
rent for duty cycles greater than 40%. In the APW7134, the
reduction of inductor peak current is recovered by a spe-
cial skill at high duty ratio. This allows the maximum in-
ductor peak current to maintain a constant level through
all duty ratio.
Main Control Loop rent have to restrict to protect the electrical circuit in the
short situation.

Application Information
where fS is the switching frequency of APW7134 and ∆IL is
the value of the worst current ripple, it can be any value of
current ripple that smaller than the worst value you can
accept. In order to perform high efficiency, selecting a low
DC resistance inductor is a helpful way. Another impor-
tant parameter is the DC current rating of the inductor.
The minimum value of DC current rating is equal to the
full load value of 600mA plus the half of the worst current
ripple, 120mA. Choosing inductors with suitable DC cur-
rent rating to ensure the inductors’ operation in the
saturation.
Due to the high switching frequency as 1.5MHz, the in-
ductor value of the application field of APW7134 is usually
from 1µH to 4.7µH. The criteria for selecting a suitable
inductor depend on the worst current ripple throughout
the inductor. The worst current ripple is defined as 40%
of the fully load capability. In the APW7134 applications,
the worst value of current ripple is 240mA, the 40% of
600mA. Evaluate L by equation (1):
The input capacitor must be able to support the maxi-
mum input operating voltage and maximum RMS input
current. The Buck converter absorbs current from input in
pulses.

waveforms is shown as Figure 2.

Application Information (Cont.)
The output voltage ripple is a significant parameter to
estimate the performance of a convertor. There are two
discrete components that affect the output voltage ripple
bigger or smaller. It is recommended to use the criterion
has mentioned above to choose a suitable inductor. Then,
based on this known inductor current ripple condition,
the output voltage ripple consists of two portions; one is
the product of ESR and inductor current ripple, and the
other is the function of the inductor current ripple and the
output capacitance. Figure 3 shows the waveforms to ex-
plain the part decided by the output capacitance.
Figure 3.
where TS is the inverse of switching frequency and the ∆IL
is the inductor current ripple. Move the COUT to the left side
to estimate the value of ∆VOUT1 as the following equation:
As mentioned above, one part of output voltage ripple is
the product of the inductor current ripple and ESR of out-
put capacitor. The equation (8) explains the output volt-
age ripple estimation.
Evaluate the ∆VOUT1 by the ideal of energy equalization.
According to the definition of Q,
Thermal Consideration
Output Capacitor Selection
APW7134 has internal over-temperature protection. When
the junction temperature reaches 150 centigrade,
APW7134 will turn off both internal power PMOSFET and
NMOSFET. The estimation of the junction temperature,
TJ, defined as below:
where the θJA is the thermal resistance of the package
utilized by APW7134.
APW7134 is a high efficiency switching converter, it means
less power loss transferred into heat. Due to the on re-
sistance difference between internal power PMOSFET
and NMOSFET, the power dissipation in the high convert-
ing ratio is greater than the low converting ratio. The worst
case is the mainly conduction loss dissipate on the inter-
nal power PMOSFET in the dropout operation. The power
dissipation nearly is defined as below:
APW7134 has the adjustable version for output voltage
setting by the users. A suggestion of maximum value of
R2 is 200kΩ for keeping the minimum current that pro-
vides enough noise rejection ability through the resistor
divider. The output voltage programmed by the following

Application Information (Cont.)
The high current paths (GND1/GND2, IN1/IN2, 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 respective IN and GND pins.
The external feedback resistors should be placed next to
the FB pins. Keep the switching nodes SW1/SW2 short
and away from the feedback network.
