Triple Chargepump For LTPS LCD
The TPS65110 TPS65111 is a very compact power supply solution providing the three voltages required by many LTPS LCD Displays
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-F 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 TPS65111 is the ultra-low output voltage ripple, as the VCC Charge Pump achieves 5-mV output ripple voltage.
