The Texas Instruments TPS651851RSLT is a single-chip power-management solution specifically designed for E Ink Vizplex enabled electronic paper displays. This PMIC generates the necessary positive and negative gate, and source driver voltages, along with back-plane bias, from a single low-voltage input supply.
Key electrical specifications include a 3-V to 6-V input voltage range and a typical current consumption of 5.5 mA. It features a boost converter for the positive rail, an inverting buck-boost converter for the negative rail, and two adjustable LDOs. The LDOs provide up to 15 V (VPOS) and -15 V (VNEG) with a current capability of 200 mA for the TPS651851 variant when VIN is 3.6 V or higher. Two charge pumps are included for the gate driver supply, capable of delivering 22 V (VDDH) and -20 V (VEE).
An adjustable VCOM driver allows for accurate panel-backplane biasing, ranging from 0 V to -5.11 V with ±1.5% accuracy. The device supports 9.7-inch and larger panel sizes. The TPS651851RSLT is housed in a 48-VQFN (6x6) package suitable for surface mounting.
This PMIC is ideal for applications requiring precise voltage generation for E-paper displays, ensuring accurate panel biasing and reliable operation. Its integrated solution simplifies design and reduces component count.
