E Ink Vizplex power management — supply range and quiescent current
The TPS65181BRGZT is a dedicated power management IC from Texas Instruments, designed for E Ink Vizplex electrophoretic displays and compatible with OMAP application processors. It integrates the multiple voltage rails and sequencing logic that an E Ink panel requires — the 3V to 6V input range covers common Li-ion and system rails, while the 5.5 mA typical supply current keeps the quiescent draw low enough that a battery-powered e-reader or label can idle for weeks between page updates.
