The TPS65180 and TPS65181 devices are single-chip power supplies designed to for E Ink VizplexTM 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 VizplexTM 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.
