TPS61097A-33
SLVSCF2A – JANUARY 2014 – REVISED DECEMBER 2014
TPS61097A-33 Low-Input Voltage Synchronous-Boost Converter With Low Quiescent
Current
1 Features
3 Description
•
The TPS61097A-33 provides a power supply solution
for products powered by either a single-cell, two-cell,
or three-cell alkaline, NiCd, or NiMH, or one-cell LiIon or Li-polymer battery. They can also be used in
fuel cell or solar cell powered devices where the
capability of handling low input voltages is essential.
Possible output currents depend on the input-tooutput voltage ratio. The devices provide output
currents up to 100 mA at a 3.3-V output while using a
single-cell Li-Ion or Li-Polymer battery. The boost
converter is based on a current-mode controller using
synchronous rectification to obtain maximum
efficiency. The maximum average input current is
limited to a value of 400 mA. The converter can be
disabled to minimize battery drain. During shutdown,
the battery is connected to the load to enable battery
backup of critical functions on the load. The device is
packaged in a 5-pin SOT-23 package (DBV)
measuring 2.8 mm × 2.9 mm.

8 Detailed Description
8.1 Overview

8.3 Feature Description
8.3.1
Controller Circuit
The device is controlled by a hysteretic current mode controller. This controller regulates the output voltage by
keeping the inductor ripple current constant in the range of 200 mA and adjusting the offset of this inductor
current depending on the output load. If the required average input current is lower than the average inductor
current defined by this constant ripple the inductor current goes discontinuous to keep the efficiency high at low
load conditions.

Figure 16. Hysteretic Current Operation
The output voltage VOUT is monitored via the feedback network which is connected to the voltage error amplifier.
To regulate the output voltage, the voltage error amplifier compares this feedback voltage to the internal voltage
reference and adjusts the required offset of the inductor current accordingly.
8.3.2 Device Enable and Shutdown Mode
The device is enabled when EN is set high and shut down when EN is low. During shutdown, the converter stops
switching and all internal control circuitry is turned off.
8.3.3 Bypass Switch
The TPS61097A-33 contains a P-channel MOSFET (Bypass Switch) in parallel with the synchronous rectifying
MOSFET. When the IC is enabled (VEN > VIH), the Bypass Switch is turned off to allow the IC to work as a
standard boost converter. When the IC is disabled (VEN < VIL) the Bypass Switch is turned on to provide a direct,
low impedance connection from the input voltage (at the L pin) to the load (VOUT). The Bypass Switch is not
impacted by Undervoltage lockout, Overvoltage or Thermal shutdown.
8.3.4 Startup
After the EN pin is tied high, the device starts to operate. If the input voltage is not high enough to supply the
control circuit properly a startup oscillator starts to operate the switches. During this phase the switching
frequency is controlled by the oscillator and the maximum switch current is limited. As soon as the device has
built up the output voltage to about 1.8 V, high enough for supplying the control circuit, the device switches to its
normal hysteretic current mode operation. The startup time depends on input voltage and load current.
8.3.5 Operation at Output Overload
If in normal boost operation the inductor current reaches the internal switch current limit threshold the main
switch is turned off to stop further increase of the input current. In this case the output voltage will decrease since
the device can not provide sufficient power to maintain the set output voltage.
If the output voltage drops below the input voltage the backgate diode of the rectifying switch gets forward biased
and current starts flow through it. Because this diode cannot be turned off, the load current is only limited by the
remaining DC resistances. As soon as the overload condition is removed, the converter automatically resumes
normal operation and enters the appropriate soft start mode depending on the operating conditions.
8.3.6 Undervoltage Lockout
An undervoltage lockout function stops the operation of the converter if the input voltage drops below the typical
undervoltage lockout threshold. This function is implemented in order to prevent malfunctioning of the converter.
The undervoltage lockout function has no control of the Bypass Switch. If the Bypass Switch is enabled
(VEN < VIL) there is no impact during an undervoltage condition, and the Bypass Switch remains on.

8.3.7 Overtemperature Protection
The device has a built-in temperature sensor which monitors the internal IC temperature. If the temperature
exceeds the programmed threshold (OTP), the device stops operating. As soon as the IC temperature has
decreased below the programmed threshold (OTP - OTP HYST), it starts operating again. There is a built-in
hysteresis to avoid unstable operation at IC temperatures at the overtemperature threshold.

9 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
9.1.1 Adjustable Bypass Switching
The EN pin can be set up as a low voltage control for the bypass switch. By setting the desired ratio of R1 and
R2, the TPS61097A-33 can be set to switch on the bypass at a defined voltage level on VIN. For example,
setting R1 and R2 to 200 KΩ would set VEN to half of VIN. The voltage level of VIN engaging the bypass switch
is based on the VIL level of EN (0.58 V). If VIN is less than 1.16 V then the bypass switch will be enabled. For
VIN values above 1.56 V (50% of VIH) the bypass switch is disabled.

9.1.2 Managing Inrush Current
Upon startup, the output capacitor of the boost converter can act as a virtual short circuit. The amount of inrush
current is dependent on the rate of increase of the input voltage, the inductance used with the converter, the
output capacitance and the parasitic circuit resistance. One method to reduce the inrush current is to use a load
switch with controlled turn-on. Texas Instruments has a large offering of controlled slew rate load switches which
can be found at www.ti.com/loadswitches. Below is an example circuit that has a load switch with controlled turnon.

Application Information (continued)
9.1.3 Thermal Considerations
Implementation of integrated circuits in low-profile and fine-pitch surface-mount packages typically requires
special attention to power dissipation. Many system-dependent issues such as thermal coupling, airflow, added
heat sinks and convection surfaces, and the presence of other heat-generating components affect the powerdissipation limits of a given component.
Three basic approaches for enhancing thermal performance are listed below.
• Improving the power dissipation capability of the PCB design
• Improving the thermal coupling of the component to the PCB
• Introducing airflow in the system
The maximum recommended junction temperature (TJ) of the TPS61097A-33 devices is 125°C. Specified
regulator operation is assured to a maximum ambient temperature TA of 85°C. Therefore, the maximum power
dissipation is about 191.7 mW. More power can be dissipated if the maximum ambient temperature of the
application is lower.

9.2.2 Detailed Design Procedure
9.2.2.1 Inductor Selection
To make sure that the TPS61097A-33 devices can operate, a suitable inductor must be connected between pin
VIN and pin L. Inductor values of 4.7 μH show good performance over the whole input and output voltage range .
Choosing other inductance values affects the switching frequency f proportional to 1/L as shown in Equation 1.

SLVSCF2A – JANUARY 2014 – REVISED DECEMBER 2014

Choosing inductor values higher than 4.7 μH can improve efficiency due to reduced switching frequency and
therefore with reduced switching losses. Using inductor values below 2.2 μH is not recommended.
Having selected an inductance value, the peak current for the inductor in steady state operation can be
calculated. Equation 2 gives the peak current estimate.

(2)
IL,MAX is the inductor's required minimum current rating. Note that load transient or over current conditions may
require an even higher current rating.
Equation 3 provides an easy way to estimate whether the device is operating in continuous or discontinuous
operation. As long as the equation is true, continuous operation is typically established. If the equation becomes
false, discontinuous operation is typically established.

(3)
Due to the use of current hysteretic control in the TPS61097A-33, the series resistance of the inductor can
impact the operation of the main switch. There is a simple calculation that can ensure proper operation of the
TPS61097A-33 boost converter. The relationship between the series resistance (RIN), the input voltage (VIN) and
the switch current limit (ISW) is shown in Equation 4.
RIN < VIN / ISW
(4)
Examples:
ISW = 400 mA, VIN = 2.5 V
(5)
In Equation 5, RIN < 2.5 V / 400 mA; therefore, RIN must be less than 6.25 Ω.
ISW = 400 mA, VIN = 1.8 V
(6)
In Equation 6, RIN < 1.8 V / 400 mA; therefore, RIN must be less than 4.5 Ω.

9.2.2.2 Capacitor Selection
9.2.2.2.1
Input Capacitor
The input capacitor should be at least 10-μF to improve transient behavior of the regulator and EMI behavior of
the total power supply circuit. The input capacitor should be a ceramic capacitor and be placed as close as
possible to the VIN and GND pins of the IC.
9.2.2.2.2
Output Capacitor
For the output capacitor C2 , it is recommended to use small ceramic capacitors placed as close as possible to
the VOUT and GND pins of the IC. If, for any reason, the application requires the use of large capacitors which
can not be placed close to the IC, the use of a small ceramic capacitor with a capacitance value of around 2.2 μF
in parallel to the large one is recommended. This small capacitor should be placed as close as possible to the
VOUT and GND pins of the IC.
A minimum capacitance value of 4.7 μF should be used, 10 μF are recommended. If the inductor exceeds 4.7
μH, the value of the output capacitance value needs to be half the inductance value or higher for stability
reasons, see Equation 7.

Using low ESR capacitors, such as ceramic capacitors, is recommended to minimize output voltage ripple. If
heavy load changes are expected, the output capacitor value should be increased to avoid output voltage drops
during fast load transients.

10 Power Supply Recommendations
The TPS61097A-33 DC-DC converters are intended for systems powered by a single up to triple cell Alkaline,
NiCd, NiMH battery with a typical terminal voltage between 0.9 V and 5.5 V. They can also be used in systems
powered by one-cell Li-Ion or Li-Polymer with a typical voltage between 2.5 V and 4.2 V. Additionally, any other
voltage source like solar cells or fuel cells with a typical output voltage between 0.9 V and 5.5 V can power
systems where the TPS61097A-33 is used. The TPS61097A-33 does not down-regulate VIN; therefore, if VIN is
greater than VOUT, VOUT tracks VIN.
11 Layout
11.1 Layout Guidelines
As for all switching power supplies, the layout is an important step in the design, especially at high peak currents
and high switching frequencies. If the layout is not carefully done, the regulator could show stability problems as
well as EMI problems. Therefore, use wide and short traces for the main current path and for the power ground
tracks. The input and output capacitor, as well as the inductor should be placed as close as possible to the IC.
Use a common ground node for power ground and a different one for control ground to minimize the effects of
ground noise. Connect these ground nodes at any place close to one of the ground pins of the IC.
The feedback divider should be placed as close as possible to the control ground pin of the IC. To lay out the
control ground, it is recommended to use short traces as well, separated from the power ground traces. This
avoids ground shift problems, which can occur due to superimposition of power ground current and control
ground current.
