Description

The TPS65186 device is a single-chip power supply designed to for E Ink Vizplex displays used in portable e-reader applications, and the device supports panel sizes up to 9.7 inches and greater. Two high-efficiency DC-DC boost converters generate ±16-V rails that 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 that 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 that can be adjusted from 0 V to 5.11 V with 9-bit control through the serial interface; it can also source or sink current depending on panel condition. The TPS65186 supports automatic panel kickback voltage measurement, which eliminates the need for manual VCOM calibration in the production line. The measurement result can be stored in nonvolatile memory to become the new VCOM power-up default value.

TPS65186 is available in a 48-pin 7-mm &times 7-mm² VQFN with 0.5-mm pitch.
