3 Description

The TPS65182x device is a single-chip power supplies designed to for E Ink Vizplex displays used in portable e-reader applications and support panel sizes up to 9.7 inches. Two high efficiency DC/DC boost converters generate ±17-V rails which are boosted to 22 V and –20 V by two change pumps to provide the gate driver supply for the Vizplex panel.
