Four regulated rails for a TFT panel
The Texas Instruments TPS65101RGER is a power-management IC purpose-built as a controller for TFT LCD displays. It delivers four regulated outputs from a single input rail spanning 2.7 V to 5.8 V — enough to generate the gate-on, gate-off, logic, and backlight bias voltages a small-to-medium TFT panel needs.
The 24-VFQFN with exposed pad (4x4 mm body) is a common QFN footprint.
The base part number is TPS65101, so date-code and revision tracking go through that root.
