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. 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.

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.

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 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. 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. 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. PEAK CURRENT REDUCTION 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. VIN Q1 Q2 OFF SWITCHED CPUMP Q3 Q4 CIN OFF ON VOUT COUT Step-Down (Buck) Mode Figure 18.

SBAS221F – DECEMBER 2001 – REVISED MARCH 2008 PROTECTION 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. 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 provides current limit to protect itself and the load. 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. CPUMP 0.22mF Enable VIN CIN 2.2mF 6 1 REG710 VOUT COUT 2.2mF 2 GND A control pin on the regulator can be used to place the device 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 quiescent current is reduced to 1µA maximum. 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 4 5 SHUTDOWN MODE CAPACITOR SELECTION 3 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. The capacitors listed in Table 1 can be used with the REG710.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) 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) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
