DESCRIPTION

The TPS65185 is a single-chip power supply designed to for E Ink^®Vizplex™ displays used in portable e-reader

applications and supports panel sizes up to 9.7 inches and greater. Two high efficiency DC/DC boost converters

generate ±16-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 that can be adjusted from 0 V to -5.11 V with 9-bit

control through the serial interface and can source or sink current depending on panel condition. The TPS65185

supports automatic panel kickback voltage measurement which eliminates the need of manual VCOM calibration

in the production line. The measurement result can be stored in non-volatile memory to become the new VCOM

power-up default value.
