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.
