Expert opinion by LDO Lakshmi · Power Management Applications Engineer (LDO / PMIC)
It generates the multiple bias rails (VGH, VGL, VCOM, logic supply) that a TFT panel needs, all in a 24-VFQFN package with an exposed thermal pad for heat sinking into the PCB ground plane.
The four outputs are internally sequenced to avoid latch-up or pixel damage during power-up and power-down — a requirement for TFT panels that the designer does not have to implement discretely.
The TPS65105 and TPS65100 are both TFT LCD bias PMICs from TI, but the TPS65105 integrates four outputs versus the TPS65100's three, adding a dedicated VCOM buffer output for panel common-voltage adjustment. Pin compatibility varies — check the respective datasheets for footprint differences.
The TPS65105RGERG4 is a lead-free (RoHS) part. The 'G4' suffix indicates TI's green/RoHS-compliant packaging.
