Texas Instruments TPS65180 Power Management ICs for E Ink® Vizplex™ Displays
The Texas Instruments TPS65180 single-chip power management IC is designed for use with E Ink® Vizplex™ displays used in portable e-reader applications and supports panel sizes up to 9.7 inches. Two high efficiency DC/DC boost converters in the TI TPS65180 generate ±17-V rails, which are boosted to 22V and –20V 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. The TPS65180 power management IC provides precise temperature measurement function to monitor the panel temperature during operation.
