3 Description
The TPS6518x and TPS65181xB family of devices
are 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. Two tracking
LDOs create the ±15-V source driver supplies which
support up to 120-mA of output current. All rails are
adjustable through the I²C interface to accommodate
specific panel requirements.
