DESCRIPTION
The TPS65182/TPS65182B 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. 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.
Accurate back-plane biasing is provided by a linear amplifier and can be adjusted either by an external resistor or
the I2C interface. The VCOM driver can source or sink current depending on panel condition.
The TPS65182/TPS65182B provides precise temperature measurement function to monitor the panel
temperature during operation. The temperature reading is updated every 60 s and can be accessed through the
I2C interface.
