DESCRIPTION
The TPS65180/TPS65181 and TPS65180B/TPS65181B family of devices are 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. For automatic
VCOM adjustment in production line, VCOM can be set from
–0.3 V to –2.5 V with 8-bit control through the serial
interface. The power switch is integrated to isolate VCOM driver from E Ink panel.
