The TPS65182/TPS65182B device is a 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.
