What the 28V input and four outputs mean for a TFT LCD power rail
The MAX8711ETE is a 4-output linear regulator from the MAX8711 series, designed specifically as a TFT LCD panel power supply. Its 28V input rail accepts the common 12V or 24V backplane supply found in industrial and medical displays, and the multiple regulated outputs bias the gate-driver, source-driver, and logic sections of the panel without separate DC-DC stages. The -40°C to 100°C operating range covers the industrial temperature band — this part sits in a display module inside a factory HMI or a medical cart that sees ambient heat from the backlight and CPU, not just room temperature.
Package and board-fit — 24-TQFN-EP (4x4) with exposed pad
Supplied in bulk packaging — no tape-and-reel, so automated pick-and-place lines need a tube or tray feeder.
Lifecycle and compliance — active, RoHS non-compliant
The RoHS status is non-compliant, so this part is not exempt under the current RoHS directive; it ships with lead-bearing solder terminations.
