A wide input supply voltage from 1.8 V to 5.5 V makes the REG710 family of devices ideal for a variety of battery sources, such as single-cell Li-Ion, or 2-cell and 3-cell nickel-based or alkaline-based chemistries. 1 • • • • Wide Input Voltage Range: 1.8 V to 5.5 V Automatic Step-Up and Step-Down Operation Low Input Current Ripple Low Output Voltage Ripple Minimum Number of External Components—No Inductors 1-MHz Internal Oscillator Allows Small Capacitors Shutdown Mode Thermal and Current Limit Protection Six Fixed Output Voltages Available: – 2.5 V, 2.7 V, 3 V, 3.3 V, 5 V, 5.5 V 2 Applications • • • • • • • • White LED Driver Smart Card Readers SIM Cards Handheld devices Modems PCMCIA Cards LCD Displays Battery Backup Supplies The input voltage may vary above and below the output voltage and the output remains in regulation. The device works as step-up or step-down converters without the need of 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 device is thermally protected and current limited, protecting the load and the regulator during fault conditions. Typical ground pin current (quiescent current) is 65 μA with no load, and less than 1 μA in shutdown mode.

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 The REG710 is a switched capacitor voltage converter that produces a regulated, low-ripple output voltage from an unregulated input voltage range from 1.8 V to 5.5 V. The high switching frequency allows the use of small surface-mount capacitors. The following section gives guidance to choose external components to complete the power supply design. Application curves are included for the typical application shown below. 9.2 Typical Applications CPUMP 0.22mF Enable VIN 3 4 6 1 5 CIN 2.2mF REG710 VOUT COUT 2.2mF 2 GND Figure 7. Typical Operating Circuit 9.2.1 Design Requirements The REG710 family of switched capacitor voltage converters offers a variety of regulated fixed output voltages. This family supports unregulated input voltages which can have values that are lower or higher than the regulated output voltage. Only input and output capacitors as well as a pump capacitor are required to have a fully functional converter. The following design procedure is adequate for the whole VIN, VOUT and load current range of REG710. 9.2.2 Detailed Design Procedure 9.2.2.1 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 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 7 for component values. With light loads or higher input voltage, a smaller 0.1-μF pump capacitor (CPUMP) and smaller 1-μF input and output capacitors (CIN and COUT, respectively) can be used. To minimize output voltage ripple, increase the output capacitor, COUT, to 10 μF or larger. The capacitors listed in Table 2 can be used with the REG710. This table is only a representative list of compatible parts. 10 Submit Documentation Feedback Copyright © 2001–2015, Texas Instruments Incorporated Product Folder Links: REG71050 REG71055 REG710 REG71050, REG71055, REG710 www.ti.com SBAS221H – DECEMBER 2001 – REVISED OCTOBER 2015 Table 2.

To minimize both input and output ripple, keep the capacitors as close as possible to the regulator using short, direct circuit traces. A suggested printed-circuit-board (PCB) routing is shown in Figure 24.

Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
