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.
