The charge pumps are optimized for a single Li-Ion cell input or for 5 V from the USB bus. The input voltage range is 3 V to 5 V for the battery voltage. High efficiency is achieved by using fractional conversion techniques for the charge pumps in combination with a power saving sleep mode. The current controlled charge pumps in addition ensure low input current ripple and low EMI. Small size external ceramic capacitors are required to build a complete power supply solution. To reduce board space to a minimum, the device switches at 1-MHz operating frequency, and is available in a small 25-ball lead free chip scale package (YZK).

Depending on the input voltage, output voltage, and output current, the charge pumps operate in different conversion modes. By switching automatically between these different modes the circuit optimizes the power conversion efficiency as well as extends operating. Operating Modes The TPS65030 contains three charge pumps and one LDO. The charge pumps for Vout2 and Vout3 as well as the LDO, used to generate Vout4, can either operate in normal mode or in sleep mode. See the SLEEP paragraph for details. The charge pumps operate in the LinSkip mode. This mode allows to switch seamlessly from the power saving pulse skip mode at light loads, to the low-noise, constant frequency linear-regulation mode, once the output current exceeds the device-specific output current threshold. This output current at which the device switches between these two operating modes is called skip current limit. In order to provide a good efficiency over a wide load range, the skip current limit is set to approximately 25% of the nominal output current for each converter. If the output current drops below the skip current threshold, the device begins to skip switching cycles which reduces its switching frequency and associated switching losses. Enable (EN1, EN2, EN3) There are 3 different enable signals available. EN1 activates the 5-V converter associated with Vbus if it is pulled high. EN2 is associated with the 3.3-V converter (Vout2) and the 1.5-V converter (Vout3). If EN2 is pulled high, the 3.3-V ramps up first, followed by the 1.5-V converter, see Figure 16. EN3 enables the 1.8-V LDO (Vout4) if pulled high. For EN3, there is an internal pull-down resistor to GND, disabling the Vout4-LDO if the EN3 pin is left open.

Timing Diagram Submit Documentation Feedback 17 TPS65030 www.ti.com SLVS620 – FEBRUARY 2006 DETAILED DESCRIPTION (continued) Soft Start The TPS65030 has an internal soft start circuit that limits the inrush current during start-up. This prevents possible voltage drops of the input voltage if a high impedance power source is connected to the input of the TPS65030. The input current for each converter is limited to about twice the nominal input current in normal operating. Switch_Enable (SW_EN1, SW_EN2) The enable pins SW_EN1 and SW_EN2 are used to activate an internal switch that connects the input for the 3.3-V charge pump and the input of the 1.5-V charge pump with either the Li-ion battery or the USB bus voltage of 5 V. SW_EN1 controls the bus switch for Vout3 (1.5 V), while SW_EN2 controls the bus switch for Vout2 (3.3 V). Vout1 and Vout4 are always battery powered. Both inputs are active high. The turnover from VI to Vbus is handled in such a way that the SW_ENx signals are used as an enable signal to the bus switch. Switchover, however, occurs based on the status of the Vbus comparator. The Vbus comparator senses the voltage at Vbus. If the voltage is above the threshold, the power source for the converters, enabled by SW_ENx is switched from the battery to the USB bus voltage. If the voltage at Vbus drops below the threshold, the power source is switched back to the battery again. The internal Vbus comparator is disabled if both SW_EN1 and SW_EN2 are low, to reduce the quiescent current of the device. Sleep The TPS65030 offers a power save mode (sleep mode), that reduces the maximum output current of the converters for Vout2, Vout3 and Vout4. The Maximum output current for each converter is reduced to 100 µA. In sleep mode, the quiescent supply current for each converter is reduced to 8 µA maximum. Sleep mode is entered when the sleep pin is pulled high. In sleep mode, all converters are switched to battery power, independent from the state of SW_EN1 and SW_EN2. In sleep mode, the charge pumps stop operation, and a separate 100-µA LDO in each converter supplies the output voltage. Power Good The power good signal is provided by an open drain output. The status of this pin depends on the status of the power good comparators for Vout2, Vout3 and Vout4. Only the converters that are enabled determine the status of the power good signal. If the output voltage of all converter that are enabled, is within its limits, the power good signal goes high. The open drain output is pulled high using an external resistor to 5.5-V maximum. If all converters are disabled, power good is held low. There is a power good delay of 3.1ms minimum after the voltage of all power rails that are enabled rose above their power good threshold. Undervoltage Lockout The undervoltage lockout circuit shuts down the device when the voltage on VIN drops below a typical threshold of 2.9 V. This prevents the device and application from damage. The UVLO circuit allows the device to start up again after the voltage on the VIN pin increased by about 80 mV. Short Circuit and Overtemperature Protection The current at the different outputs are limited. When the junction temperature exceeds 155°C, the device shuts down to protect the device from damage. After the temperature decreased to about 135°C, the device starts up if it is still enabled. In order to reduce the quiescent current, the overtemperature protection is disabled in sleep-mode. TEST Input SRP Enable The TEST input SRP enable pin has two functions. It is an output when the device is in test mode or an input in normal mode. In order to test the electrical connections between the power supply chip (TPS65030) and the USB-OTG 18 Submit Documentation Feedback TPS65030 www.ti.com SLVS620 – FEBRUARY 2006 DETAILED DESCRIPTION (continued) transceiver (TUSB6010), a test mode is available on TPS65030. The TEST pin is used as an output to TUSB6010. This test mode is entered when EN_SW1 and EN_SW2 and SLEEP are high at the same time. In this case the actual function of SLEEP is disabled and the output pin TEST is changed from high-impedance state to low in case that EN1=1. For all other conditions of EN_SW1, EN_SW2, SLEEP, and EN1 it stays in high impedance state, see Table 1. The test mode should be entered with the following sequence: • set SLEEP = 0 • set EN1 = 0 • make sure Vbus is not supplied from external source (Vbus < 4.3 V) • set SW_EN1 = SW_EN2 = 1 • set SLEEP = 1 (this enters the test mode) • toggle EN1 to switch between low and high impedance on TEST output pin Table 1.

SLEEP_INT SLEEP EN_SW1 EN_SW2 TM2 TEST EN1 Figure 17. When the device is in normal mode (not in test mode), the pin is used as an input to enable or disable the SRP feature of the Vbus charge pump. If the TEST SRP pin is held low, the SRP feature is enabled and the charge pump starts up with a current limit of 1 mA until the voltage at Vbus reaches 2.5 V. If the voltage exceeds 2.5 V, the current limit is increased to a higher value in order to provide 100 mA of output current. If SRP is pulled high, the charge pump starts with a higher current limit even for Vbus < 2.5 V in order to provide enough output current to start into a 100 mA load. Submit Documentation Feedback 19 TPS65030 www.ti.com SLVS620 – FEBRUARY 2006 Theory or Operation / Design Procedure Charge Pump Operation (Based on Vout3 Step-Down Converter) The description of how the charge pumps operate is based on the design of the step-down charge pump used for Vout3. This converter either operates in a LDO mode for input voltages (battery voltage) lower than 3.5 V. If the input voltage exceeds 3.5 V, the converter operates as a step-down charge pump. As the efficiency of a charge pump mainly depends on the input, output voltage ratio and its operating mode (LDO or x1/2), the efficiency graph shows a typical sawtooth waveform. This is caused by the fact that the charge pump can only increase efficiency if it switches to a different operating mode but not by adjusting its duty cycle like in inductive converters, where the efficiency curve is smooth LDO Conversion Mode In the LDO mode the flying capacitor is not used for transferring energy. The switches 3 and 4 are closed and connect the input directly with the output. This mode is automatically selected if the input voltage is too low to provide enough output voltage in x1/2 charge pump mode. In LDO mode the regulation is done by regulating the current through switch 4. For an output current of less than 20 mA, the current through switch is turned on and off like in SKIP mode regulation. X1/2 Conversion Mode This conversion mode is internally selected if the input to output voltage ratio is greater than 2. In the first switching cycle, the flying capacitor is charged in series with the output capacitor. In the second cycle the flying capacitor is connected in parallel with the output capacitor which discharges the flying capacitor and charges the output. Regulation is done similar to LDO mode by regulating the current through switch 4. For an output current less than the SKIP current threshold, switch 4 does not turn on each switching cycle unless energy is needed at the output. The device now operates in skip mode with a lower switching frequency, depending on the load current. VO VO 1 3 1 3 Cfly Cfly VI VI 4 + 4 2 + 2 X2 Conversion Mode This conversion mode applies to the converter used to generate Vout2. It is used to generate an output voltage that is higher than the input voltage. In the first switching cycle, the flying capacitor is charged in parallel to the input voltage. In the second switching cycle, the flying capacitor is connected in series with the input voltage, charging the output capacitor to twice the input voltage. Regulation of the output voltage is done similar to the other conversion modes. Sleep-Mode LDO In sleep mode, a separate LDO in the charge pump block, supplied from the battery, is used to provide the output voltage. 20 Submit Documentation Feedback TPS65030 www.ti.com SLVS620 – FEBRUARY 2006 Theory or Operation / Design Procedure (continued) Capacitor Selection Ceramic capacitors such as X5R or X7R are recommended to be used with TPS65030. Low ESR capacitors on VOUTx reduce the ripple voltage on the output of the supplies. Table 2 lists capacitor types that have been tested with the TPS65030. For the flying capacitors, the value is not critical. For values lower than those listed in the recommended table, the performance of the converter decreases with regard to maximum output current at minimum input voltage. It also causes the converter to switch to its lower efficient mode at a higher input voltage. The value of the output capacitors is critical for stability. A high dc-bias voltage at ceramic capacitors causes a lower capacitance than expected. This effect is critical for Vbus with an output voltage of 5 V. The Vbus converter is designed to operate with a minimum capacitance of 3 µF. In order to keep the minimum capacitance at Vbus above 3 µF, a voltage rating for Cout1 of more than 6.3 V may be required, depending on the specification given by its manufacturer. Table 2.
