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.
