TFT bias supply in a 24-HTSSOP
The TPS65105PWP is a Texas Instruments controller IC purpose-built for TFT LCD bias generation, delivering four regulated outputs from a single 2.7V to 5.8V input rail. Four outputs means one IC handles the positive gate voltage (VGH), negative gate voltage (VGL), the VCOM driver, and the logic supply — no separate boost, inverter, and LDO. The 24-TSSOP with exposed pad (24-HTSSOP) sinks the heat from the integrated power switches into the PCB copper, which matters when the panel is running at full brightness in a sealed enclosure.
Industrial temperature grade and sourcing posture
The active lifecycle status means TI is still manufacturing the part — no last-time-buy clock ticking, no PCN-driven scramble for the next lot. The ROHS3 compliance covers current EU and global RoHS exemptions — no conflict with a typical lead-free assembly profile.
What the four outputs mean for the BOM
A TFT panel typically needs a positive gate-drive rail, a negative gate-drive rail, a VCOM buffer, and a logic supply. The TPS65105PWP integrates all four regulators into one controller, eliminating three discrete DC-DC converters and their associated components.
