All three regulated outputs are generated using a charge pump topology. The VCC charge pump provides precise, high efficiency, and very low ripple dc/dc conversion for the LCD analog power. The VCC boost ratio (x1.0, x1.33, x1.5, and x2.0) is automatically set based on input and output voltage conditions. The VCC output assures 16 mA of current by using three 0.22-µF flying capacitors. If the required output current is smaller, smaller capacitors can be applied. The VDD charge pump provides a higher positive voltage, and the VSS charge pump provides the negative output voltage. Power up/down sequences are internally set and are secured even in cases of sudden and abnormal VIN drop. One of the most significant features of the TPS65110/11 is the ultra-low output voltage ripple, as the VCC charge pump achieves 5-mV output ripple voltage.

TPS65110 automatically sets the boost ratio based on input and output voltage conditions. For example, when the input voltage from a battery becomes lower, the device automatically increases the boost ratio from x1.33 to x1.5. In a fixed input voltage mode, the device provides for higher conversion efficiency; for example, in the case of 2.8 V to 3.3 V conversion or 2.8 V to 5.0 V conversion. In this case, the VCC charge pump can enter into a SKIP mode operation in order to maintain the efficiency of a low load condition. The highest frequency of the charge pump is 400 kHz (typ). The charge pump operates by using higher frequencies in the heavier load current conditions, and decreases the frequency in the lighter load conditions. Maximum output current and operating frequency characteristics are dependent on external conditions such as the flying capacitor, output capacitor, and ambient temperature range. VIN [V] VCC[V] 2.4 2.5 2.6 2.7 2.8 2.9 3.0 3.1 3.2 3.3 x1.5 x1.33 5.0 NA x2 3.3 3.4 3.5 3.6 3.7 3.8 3.9 4.0 4.1 4.2 4.4 4.6 4.8 5.0 5.2 5.4 5.5 x1 x1.5 x1.33 x1 NOTE: Gray portion is HYSTERESIS. Of importance, the VCC charge pump is also used as the power source for the VDD and VSS charge pumps. Therefore, consider a case where the VDD charge pump’s output current is required to be 2mA, and the boost ratio is x3. With this condition, the required (additional) current for the VCC output is slightly more than 6 mA. If the VSS charge pump output current requirement is 1 mA, then the (additional) required current from VCC is another 1 mA. (Note: the VCC charge pump maintains a minimum of 16-mA output capability in addition to the loads required to support the VDD and VSS charge pumps under the recommended conditions.) VDD Charge Pump The power source for the VDD charge pump is the VCC charge pump. The output voltage and boost ratio of the VDD charge pump are fixed at either a 7.5 V and x3 boost (TPS65110), or a 9.0 V and x2 boost (TPS65111). The topology of this charge pump is SKIP mode, and the maximum frequency is 400 kHz. Maximum output current is dependent on the flying capacitors and ambient temperature range (refer to the typical characteristics). VSS Charge Pump The VSS charge pump is powered from the VCC charge pump and has a fixed output voltage of either –2.7 V (TPS65110) or –3.0 V (TPS65111). The boost ratio for the VSS charge pump is fixed at x−1. The operation topology is SKIP mode and has a maximum frequency of 400 kHz. Maximum output current is dependent on the flying capacitor and ambient temperature range (refer to the typical characteristics). UVLO − Under Voltage Lockout The UVLO provides for the save operation of the device. It prevents the converter from turning on when the voltage on the VIN pin is less than the threshold voltage of UVLO. Note that although the input voltage range of the product is shown to be down to 2.4 V, the maximum threshold of the UVLO for a rising VIN is 2.5 V. Therefore, to operate down to 2.4 V, the device must first be powered by a source of more than 2.5 V. Enable Low logic on the EN pin forces the TPS6511x into shutdown mode. In shutdown, the power switch, drivers, voltage reference, oscillator, and all other functions are turned off. The supply current is reduced to less than 1 µA in shutdown mode. Power-Up and Power-Down Sequencing The TPS65110/11 controls power-up and power-down sequence through an enable pin. This signal should be terminated and not be left floating to prevent miss-operation. Power-Up Sequence When the enable pin EN is pulled high, the device starts its power on sequencing. The VCC output starts up first. When the output voltage VCC has reached 75% of its nominal value, the VSS output comes up next. When VSS has reached 75% of the nominal value, the positive output VDD finally comes up. 11 www.ti.com SLVS495 − SEPTEMBER 2003 Power-Down Sequencing When the enable pin EN is pulled low, the device starts its power-down sequencing. The VDD output goes down first. When the output voltage VDD has reached 70% of its nominal value, the VSS output goes down next. When VSS has reached 70% of the nominal value, the positive output VCC finally goes down. The TPS6511x ensures this power-down sequence even in the case of a sudden VI drop. 2.3 V VIN EN 1 2 1 1 1 2 Vref (Internal) x0.75 VCC 2.2 V 3 x0.75 3 3 4 3 VSS x0.7 x0.7 4 x0.7 2 x0.7 VDD 12 1 x0.7 5 x0.7 SYS_EN (Internal) 2 4 1 2 Power Sequence PACKAGE OPTION ADDENDUM www.ti.com 30-Mar-2005 PACKAGING INFORMATION Orderable Device Status (1) Package Type Package Drawing Pins Package Eco Plan (2) Qty Lead/Ball Finish MSL Peak Temp (3) TPS65110RGE ACTIVE QFN RGE 24 92 TBD CU SN Level-2-235C-1 YEAR TPS65110RGER ACTIVE QFN RGE 24 3000 TBD CU SN Level-2-235C-1 YEAR TPS65110RGERG4 ACTIVE QFN RGE 24 3000 Green (RoHS & no Sb/Br) CU NIPDAU Level-2-260C-1 YEAR TPS65111RGE ACTIVE QFN RGE 24 150 TBD CU SN Level-2-235C-1 YEAR TPS65111RGER ACTIVE QFN RGE 24 3000 TBD CU SN Level-2-235C-1 YEAR (1) The marketing status values are defined as follows: ACTIVE: Product device recommended for new designs.
