It takes a 2.5V to 5.5V input and generates the three or four supply rails a TFT display needs: a main output adjustable up to 20V, a negative rail adjustable down to -18V, and two auxiliary regulated outputs (3V to 5.6V). Without it, the junction temperature climbs fast under load. ## Industrial temp range and adjustable rails The wide input range (2.5V to 5.5V) lets it run from a single lithium cell or a 3.3V/5V system rail without a separate pre-regulator. The negative rail capability (adjustable down to -18V) is what separates this from single-output DDR converters like the TPS53317RGBR or TPS51100DGQ. Those parts are DDR memory termination regulators — one output, no negative rail. ## Package rework and pad layout The centre pad is the main heat path and the ground return — lift the part by heating from underneath the board, not by prying.","metaTitle":"TPS65120RGTT – TI TFT LCD Bias Supply, 4-Output PMIC, 16-QFN","metaDescription":"Texas Instruments TPS65120RGTT – 4-output TFT LCD converter, 2.5V–5.5V input, adjustable ±18V rails, 16-VFQFN exposed pad.

The TPS65120RGTT includes a negative rail adjustable down to -18V, alongside a positive rail adjustable up to 20V and two auxiliary outputs in the 3V to 5.6V range. This makes it suitable for TFT LCD gate and source bias where a negative VGL rail is required."},{"question":"Is TPS65120RGTT a replacement for TPS53317RGBR or TPS51100DGQ?","answer":"No. The TPS53317RGBR and TPS51100DGQ are single-output DDR memory termination regulators (VTT). The TPS65120RGTT is a four-output TFT LCD bias converter with positive and negative rails.
