Wide Input Range: 1.8V to 5.5V
The REG710 is a switched capacitor voltage converter,
that produces a regulated, low-ripple output voltage from
an unregulated input voltage. A wide-input supply voltage
of 1.8V to 5.5V makes the REG710 ideal for a variety of
battery sources, such as single cell Li-Ion, or two and three
cell nickel- or alkaline-based chemistries.
Automatic Step-Up/Step-Down Operation
Low Input Current Ripple
Low Output Voltage Ripple
Minimum Number of External
ComponentsNo Inductors
1MHz Internal Oscillator Allows Small
Capacitors
The input voltage may vary above and below the output
voltage and the output will remain in regulation. It works
equally well for step-up or step-down applications without
the need for an inductor, providing low EMI DC/DC
conversion. The high switching frequency allows the use
of small surface-mount capacitors, saving board space
and reducing cost. The REG710 is thermally protected and
current limited, protecting the load and the regulator during
fault conditions. Typical ground pin current (quiescent
current) is 65µA with no load, and less than 1µA in
shutdown mode. The 5.5V version of the REG710 is
available in a thin TSOT23-6 package. All other versions
are available in a small SOT23-6 package.

This integrated circuit can be damaged by ESD. Texas
Instruments recommends that all integrated circuits be
handled with appropriate precautions. Failure to
observe proper handling and installation procedures can cause
damage.

ESD damage can range from subtle performance degradation to
complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could
cause the device not to meet its published specifications.
NOTE: (1) Stresses above these ratings may cause permanent damage. Expo-
sure to absolute maximum conditions for extended periods may degrade device
reliability.

SBAS221E − DECEMBER 2001 − REVISED SEPTEMBER 2003
THEORY OF OPERATION
The REG710 regulated charge pump provides a regulated
output voltage for input voltages ranging from less than the
output to greater than the output. This is accomplished by au-
tomatic mode switching within the device. When the input
voltage is greater than the required output, the unit functions
as a variable frequency switch-mode regulator. This opera-
tion is shown in Figure 1. Transistors Q1 and Q3 are held off,
Q4 is on, and Q2 is switched as needed to maintain a regu-
lated output voltage.
During the second half cycle the FET switched are config-
ured as shown in Figure 2B, and the voltage on CPUMP is
added to VIN. The output voltage is regulated by skipping
clock cycles as necessary.
PEAK CURRENT REDUCTION
In normal operation, the charging of the pump and output
capacitors usually leads to relatively high peak input cur-
rents which can be much higher than that of the average
load current. The regulator incorporates circuitry to limit
the input peak current, lowering the total EMI production of
the device and lowering output voltage ripple and input cur-
rent ripple. Input capacitor (CIN) supplies most of the
charge required by input current peaks.

PROTECTION
The regulator has thermal shutdown circuitry that protects
it from damage caused by overload conditions. The ther-
mal protection circuitry disables the output when the junc-
tion temperature reached approximately 160°C, allowing
the device to cool. When the junction temperature cools to
approximately 140°C, the output circuitry is automatically
reenabled. Continuously running the regulator into thermal
shutdown can degrade reliability. The regulator also pro-
vides current limit to protect itself and the load.
COUT
Step−Down (Buck) Mode
Figure 1. Simplified Schematic of the REG710
Operating in the Step-Down Mode
When the input voltage is less than the required output
voltage, the device switches to a step-up or boost mode of
operation, as shown in Figure 2.
SHUTDOWN MODE
A control pin on the regulator can be used to place the de-
vice into an energy-saving shutdown mode. In this mode,
the output is disconnected from the input as long as VIN is
greater than or equal to minimum VIN and the input quies-
cent current is reduced to 1µA maximum.
A conversion clock of 50% duty cycle is generated. During
the first half cycle the FET switches are configured as
shown in Figure 2A, and CPUMP charges to VIN.

The approximate efficiency is given by:
CAPACITOR SELECTION
Efficiency (%) = VOUT/(2 × VIN) × 100
For minimum output voltage ripple, the output capacitor
COUT should be a ceramic, surface-mount type. Tantalum
capacitors generally have a higher Effective Series Resist-
ance (ESR) and may contribute to higher output voltage
ripple. Leaded capacitors also increase ripple due to the
higher inductance of the package itself. To achieve best
operation with low input voltage and high load current, the
input and pump capacitors (CIN and CPUMP, respectively)
should also be surface-mount ceramic types. In all cases,
X7R or X5R dielectric are recommended. See the typical
operating circuit shown in Figure 3 for component values.

LAYOUT
Large transient currents flow in the VIN, VOUT, and GND
traces. To minimize both input and output ripple, keep the
capacitors as close as possible to the regulator using
short, direct circuit traces.
Figure 3. Typical Operating Circuit
With light loads or higher input voltage, a smaller 0.1µF
pump capacitor (CPUMP) and smaller 1µF input and output
capacitors (CIN and COUT, respectively) can be used. To
minimize output voltage ripple, increase the output capaci-
tor, COUT, to 10µF or larger.
A suggested PCB routing is shown in Figure 4. The trace
lengths from the input and output capacitors have been
kept as short as possible.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
