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.

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 TPS65182x 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.
