5-output TFT LCD regulator — 4.5V to 30V input, 0.8V to 40V output
The LT3513EUHF#PBF is a five-output regulator IC from Analog Devices designed specifically for TFT LCD panel power. It integrates the switching converters and linear regulators needed to generate the multiple supply rails a typical LCD panel requires — gate-on, gate-off, source, logic, and backlight bias — from a single 4.5V to 30V input rail. The output voltage range spans 0.8V to 40V, covering the positive and negative bias levels common in TFT LCD applications. The -40°C to 125°C operating temperature range suits it for outdoor or industrial displays where the panel sees wide ambient swings.
Package and thermal — 38-QFN with exposed pad
Housed in a 38-lead WFQFN with exposed pad (5x7 mm body), the LT3513EUHF#PBF relies on the bottom-side thermal pad for heat sinking. The tube packaging is the standard delivery format for this part. Surface-mount assembly follows standard QFN reflow profiles; the exposed pad requires a solder paste stencil aperture matching the pad area to avoid voids.
