Triple-rail charge pump for LTPS LCD bias
The Texas Instruments TPS65110RGERG4 is a triple-output charge pump designed specifically for LTPS LCD panel bias sequencing. It delivers three regulated rails from a single 2.4V to 5.5V input: -2.7V, 3.3V, and 7.5V. The three outputs cover the gate-on, gate-off, and source-driver supply voltages needed by low-temperature polysilicon LCDs. The 3.3V rail can also serve as a logic supply for the panel timing controller.
24-VFQFN exposed pad — rework profile matters
Rework on this package is straightforward with a hot-air station if the board has a solder-mask-defined pad. Pre-bake the board at 125°C for 4 hours if it has been exposed to humidity — the VQFN can trap moisture under the pad and pop during reflow.
Obsolete — no official successor listed
The TPS65110RGERG4 carries a lifecycle status of Obsolete per Texas Instruments.
