DESCRIPTION

•
Wide Input Range: 1.8V to 5.5V
Automatic Step-Up/Step-Down Operation
Low Input Current Ripple
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.
•
•
•
•
Low Output Voltage Ripple
Minimum Number of External
Components—No Inductors
•
1MHz Internal Oscillator Allows Small
Capacitors
The input voltage may vary above and below the
output voltage and the output remains 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.

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.

THEORY OF OPERATION
During the second half cycle the FET switched are
configured as shown in Figure 19B, and the voltage
on CPUMP is added to VIN. The output voltage is
regulated by skipping clock cycles as necessary.
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 automatic mode switching
within the device. When the input voltage is greater
than the required output, the unit functions as a
PEAK CURRENT REDUCTION
variable frequency switch-mode regulator. This
operation is shown in Figure 18. Transistors Q1 and
Q3 are held off, Q4 is on, and Q2 is switched as
needed to maintain a regulated output voltage.
In normal operation, the charging of the pump and
output capacitors usually leads to relatively high peak
input currents 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 current ripple. Input
capacitor (CIN) supplies most of the charge required
by input current peaks.
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 19.
A conversion clock of 50% duty cycle is generated.
During the first half cycle the FET switches are
configured as shown in Figure 19A, and CPUMP
charges to VIN.

PROTECTION
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 20 for
component values.
The regulator has thermal shutdown circuitry that
protects it from damage caused by overload
conditions. The thermal protection circuitry disables
the output when the junction temperature reaches
approximately +160°C, allowing the device to cool.
CPUMP
When
the
junction
temperature
cools
to
0.22mF
approximately +140°C, the output circuitry is
automatically reenabled. Continuously running the
regulator into thermal shutdown can degrade
reliability. The regulator also provides current limit to
protect itself and the load.

SHUTDOWN MODE
GND
2
The EN pin enables the IC when pulled high and
places it into energy-saving shutdown mode when
pulled low. When in shutdown mode, the output is
disconnected from the input and the quiescent current
is reduced to 0.01µA typical. This shutdown mode
functionality is only valid when VIN is above the
minimum recommended operating voltage. The EN
pin cannot be left floating and must be actively
terminated either high or low.
Figure 20. 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 capacitor, COUT, to 10µF or
larger.
CAPACITOR SELECTION
For minimum output voltage ripple, the output
capacitor COUT should be a ceramic, surface-mount
type. Tantalum capacitors generally have a higher
effective series resistance (ESR) and may contribute
to higher output voltage ripple. Leaded capacitors
also increase ripple due to the higher inductance of

EFFICIENCY
LAYOUT
The efficiency of the charge pump regulator varies
with the output voltage version, the applied input
voltage, the load current, and the internal operation
mode of the device.
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.
The approximate efficiency is given by:
A suggested printed circuit board (PCB) routing is
shown in Figure 21. The trace lengths from the input
and output capacitors have been kept as short as
possible.
Efficiency (%) = VOUT/(2 ´ VIN) ´ 100

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46C and to discontinue any product or service per JESD48B. Buyers should
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All
semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time
of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which
have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such
components to meet such requirements.
