E-paper display power — 5.5 mA supply current sets the battery budget
The TPS65180BRGZR is a power-management IC from Texas Instruments designed specifically for E Ink® Vizplex™ displays. Its 5.5 mA supply current is the number that matters for a portable e-reader or shelf-label design — that quiescent draw defines how long the battery lasts between page updates. The 3 V to 6 V supply range covers a single-cell Li-ion (3.7 V nominal) or a regulated 5 V rail, so the power tree is straightforward.
48-VFQFN — layout checklist for the exposed pad
The 48-VFQFN Exposed Pad package (7x7 mm, 0.50 mm pitch) demands a thermal-via array under the centre pad for heat sinking. Surface-mount reflow profile follows standard lead-free solder profiles for QFN packages.
