TPS65642YFFR

The Texas Instruments TPS65642YFFR is an active LCD Bias IC featuring an integrated Gamma Reference, suitable for notebook PCs and tablet PCs. This device integrates multiple power rails including synchronous boost converters for AV DD, a non-synchronous boost converter for V GH with temperature compensation, synchronous buck converters for V CORE and V IO1, and a low-dropout linear regulator for V IO2.

Key electrical specifications include an input voltage range of 2.6V to 6V and source driver voltages ranging from 6V to 9.1V. The IC supports an I2C interface for control and features adjustable sequencing, gamma buffer, output discharge, and a reset generator. It also includes a temperature sensor or compensation mechanism and supports both GIP and Non-GIP displays.

The TPS65642YFFR is housed in a compact 56-ball DSBGA package measuring 3.16 mm x 3.45 mm with a 0.4 mm pitch. Its operating temperature range is -40°C to 85°C, making it suitable for a variety of environmental conditions. The device also incorporates a programmable V COM calibrator with two integrated buffer amplifiers and 14-channel, 10-bit programmable gamma voltage correction.
