Product details

E Ink display power — what the TPS65185RGZT is built for

The TPS65185RGZT is a Texas Instruments power-management IC purpose-built for E Ink® Vizplex™ displays, listed under the E Ink and Vizplex series. The input supply range spans 3 V to 6 V, covering single-cell Li-ion, two-cell alkaline, or a regulated rail. The IC itself draws 5.5 mA typical supply current.

Temperature grade and operating envelope

The lower bound at -10°C is above military-grade but sufficient for warehouse or cold-chain logistics terminals that are not freezer-rated.

Housed in a VFQFN with exposed pad (supplier package 48-VQFN, 7x7 mm), the part requires a solder-paste stencil opening under the centre pad for thermal and electrical ground connection. The pad also serves as the primary heat path — the datasheet layout recommendation should be followed to keep junction temperature within limits.

ROHS3 compliant.

Frequently asked questions

What is the TPS65185RGZT used for?

It is a power-management IC designed specifically for E Ink® Vizplex™ electrophoretic displays. It generates the multiple voltage rails (gate, source, VCOM) and handles the power sequencing that an e-paper panel requires, so it is the primary power device in e-readers, electronic shelf labels, and signage boards using E Ink technology.
