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.
