产品概述
The TPS6518x and TPS65181xB 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.The TPS6518x and TPS65181xB devices provide precise temperature measurement function to
monitor the panel temperature during operation. The TPS65180 and TPS65180B requires the host
processor to trigger the temperature acquisition through an I2C write
whereas the TPS65181 and TPS65181B automatically updates the temperature every 60 s.
