TPS651851RSLR General Description

The TPS65185x 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 120/200 mA (TPS65185/TPS651851) 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 source or sink current depending on panel condition. The TPS65185x 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 non-volatile memory to become the new VCOM power-up default value.

TPS65185 is available in two packages, a 48-pin 7-mm × 7-mm² VQFN (RGZ) with 0.5-mm pitch, and a 48-pin 6-mm × 6-mm² VQFN (RSL) with 0.4-mm pitch. The TPS651851 is available in a 48-pin 6-mm × 6-mm² VQFN (RSL) with 0.4-mm pitch.
