Introduction

AI Translation

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.
