Display power stage — input rail and thermal budget
The TPS65167RHAT is a Texas Instruments power management IC built for LCD TV and monitor applications. It operates from a 6V to 14V supply rail, which matches the typical intermediate bus in a switched-mode power supply feeding the display driver board. The Tape & Reel delivery suits automated pick-and-place for medium-to-high volume builds.
Package and board integration — 40-VQFN with exposed pad
The 40-VFQFN exposed pad package (supplier device package 40-VQFN 6x6 mm) requires a thermal land pattern on the PCB with solder paste coverage matching the datasheet recommendation. The pad is the primary heat path — without a solid ground-plane connection the junction temperature rises above the 85°C ceiling in a panel running at full backlight. Surface-mount assembly is standard; the exposed pad does not add reflow complexity beyond ensuring adequate solder volume under the die attach area.
