1.5MHz, 1.3A, High-Efficiency
Synchronous-Rectified Buck Converter
Features
General Description
The uP1722 is a high efficiency synchronous-rectified buck
converter with internal power switches. Fixed 1.5MHz PWM
operation allows possible smallest output ripple and
external component size. With high conversion efficiency
and small package, the uP1722 is ideally suitable for
portable devices and USB/PCIE-based interface cards
where PCB area is especially concerned.

With internal low RDS(ON) switches, the uP1722 is capable
of delivering 1.3A peak output current over a wide input
voltage range from 2.6V to 5.5V. The output voltage is
adjustable from 0.6V/0.5V (uP1722P/uP1722Q) to VIN by
a voltage divider. Other features include internal soft-start,
chip enable, under-voltage, over-temperature and over-

Application Information
Output Inductor Selection
Input Capacitor Selection
The uP1722 draws pulsed currewith sharp edges from
the input capacitor resulting in ripple anoise at the input
supply voltage. A minimum 4.X5R or X7R ceramic
capacitor is highly recommend the pulsed current.
The input capacitor should be plas near the device as
possible to avoid the stray ductanalong the connection
trace. Y5V dielectrics, asidom losing most of their
capacitance over temature, they also become resistive
at high frequencies. This es their ability to filter out
high frequency noi
Output inductor selection is usually based on the
considerations of inductance, rated current value, size
requirements andDC resistance (DCR).
The inductance is chosen based on the desired ripple
current. Large value inductors result in lower ripple currents
and small value inductors result in higher ripple currents.
Higher VIN or VOUT also increases the ripple current as shown
in the equation below.Areasonable starting point for setting
ripple current is ∆IL = 390mA (30% of 1.3A). For most
applications, the value of the inductor will fall in the range
of 1uH to 10uH.
The capacitor witlow ES(equivalent series resistance)
provides the smarop voltage to stabilize the input voltage
during the transient loing. For input capacitor selection,
the ceramicitors larger than 4.7uF is recommend.

The aximuS ripple current is calculated as:

∆IL =

fOSC × LOUT
Maximum current ratings of the inductor are generally
specified in two methods: permissible DC current and
saturation current. PermissibleDC current is the allowable
DC current that causes 40OC temperature raise. The
saturation current is the allowable current that causes 10%
inductance loss. Make sure that the inductor will t
saturate over the operation conditions including temperat
range, input voltage range, and maximum output current.

1.0A so that it will not saturate even under current imit

ripple current ratings are often based on 2000 hours of life.
is makes it advisable to further derate the capacitor, or
choose a capacitor rated at a higher temperature than
required. Always consult the manufacturer if there is any
question.
The size requirements refer to the area and heigh
requirement for a particular design. For better cy,
choose a low DC resistance inductor. DCly
inversely proportional to size.
Output Capacitor Selection
The uP1722 is specifically design to operate with minimum
4.7uF X5R or X7R ceramic capacitor. The value can be
increased to improve load/line transient performance. Y5V
dielectrics, aside from losing most of their capacitance over
temperature, they also become resistive at high
frequencies. This reduces their ability to filter out high
frequency noise.
Different core materials and shapes ill change the size/
current and price/current relationshof an indur. Toroid
or shielded pot cores in ferrite or pemalloy marials are
small and don’t radiate much energy, gerally cost
more than powdered iron core inductors with similar electrical
characteristics. The choice which style inductor to use
often depends on the price vs. srequirements and any
radiated field/EMI requirets.
The ESR of the output capacitor determines the output
ripple voltage and the initial voltage drop following a high
slew rate load transient edge. The output ripple voltage
can be calculated as:

avoiding the uP1722 from exceeg the maximum junction
temperature. In typical applications, e conduction loss
dominates the total power loss iuP1722. The conduction
loss has its maximum at high uty, low input voltage,
and high ambient temperaturs.
The ceramic capacitor with low ESR value provides the low
output ripple and low size profile. Connect a 4.7uF ceramic
capacitor at output terminal for good performance and place
the input and output capacitors as close as possible to the
device.
Consider the uP1722 in drout mode operation at an input
voltage of 2.6V, a load curren400mA and an ambient
temperature of 75OC. on-resistance of the upper switch
is about 500mΩ at this coion. Therefore the power
dissipation PD is:
Using Ceramic Capacitors
Higher value, lower cost ceramic capacitors are now
available in smaller case sizes. Their high ripple current,
high voltage rating and low ESR make them ideal for
switching regulator applications. Because the uP1722
control loop does not depend on the output capacitor’s ESR
PD = IO2 UT × RDS) = 80mW
This results 50 x 0.08 = 20OC temperature raise at
junction. ctn temperature is 95OC and is lower
than its maum ting 125OC.
for stable operation, ceramic capacitors can be used to
achieve very low output ripple and small circuit size.
However, care must be taken when these capacitors are
used at the input and the output. When a ceramic capacitor
is used at the input and the power is supplied by a wall
adapter through long wires, a load step at the output can
induce ringing at the input, VIN. At best, this ringing can
couple to the output and be mistaken as loop instabilityt
worst, a sudden inrush of current through the long wire
can potentially cause a voltage spike at VIN, large enough
to damage the part.
CheckTransient Response
The loop response can be checked by looking at
the lsient response. Switching regulators take
veral cycles to respond to a step in load current. When
a loatep occurs, VOUT immediately shifts by an amount
equal to (∆IOUT x ESR), where ESR is the effective series
retance of COUT. ∆IOUT also begins to discharge or charge
COUT, which generates a feedback error signal. The regulator
p then acts to return VOUT to its steady state value.
During this recovery time, VOUT can be monitored for
overshoot or ringing that would indicate a stability problem.
When choosing the input and output ceramic capaors,
choose the X5R or X7R dielectric formulations. The
dielectrics have the best temperature and tage
characteristics of all the ceramics for a gived
size.
Thermal Considerations
In most applications, the uP1722 ds not disste much
heat due to its high efficiency. Howeer, overteperature
protection is implemented in case of ons where
the uP1722 is operating at high ambient temperature. If
the junction temperature reaes approximately 150OC, the
OTP turns both power switches aet the LX node become

PCB Layout Considerations
High switching frequencies and relatively large peak
currents make the PCB layout a very important part of
switching mode power supply design. Good design
minimizes excessive EMI on the feedback paths and voltage
gradients in the ground plane, both of which can result in
instability or regulation errors. Follow the PCB layout
