The TPS65181BRGZR from Texas Instruments is a single-chip power management solution tailored for E Ink Vizplex electronic paper displays, supporting panel sizes up to 9.7 inches. It operates from a single, low-voltage input supply ranging from 3V to 6V.
This PMIC generates positive and negative gate and source driver voltages, along with back-plane bias. Key features include a boost converter for the positive rail, an inverting buck-boost converter for the negative rail, two adjustable LDOs providing ±15V at 120mA for source driver supplies, and two charge pumps generating ±22V and -20V for gate driver supplies. An adjustable VCOM driver supports accurate panel back-plane biasing.
All output rails are adjustable via an I2C serial interface, allowing for specific panel requirements. The device also includes a 3.3V power switch for disabling system power rails and thermistor monitoring. It is housed in a thermally-enhanced 48-VQFN (7x7 mm) package suitable for surface mounting.
The TPS65181BRGZR is designed for applications such as EPD power supplies, e-book readers, and systems utilizing EPSON timing controllers or application processors with integrated timing controllers.
