TPS651851RSLR

The Texas Instruments TPS651851RSLR is a specialized Power Management Integrated Circuit (PMIC) designed for E-Ink Vizplex enabled electronic paper displays. It provides a single-chip power-management solution, generating positive and negative gate, source driver voltages, and back-plane bias from a single low-voltage input supply.

Key electrical specifications include an input voltage range of 3V to 6V and a typical quiescent current of 5.5mA. The device offers 4 regulated outputs, including two step-up DC/DC converters and two adjustable LDOs. The LDOs provide up to 15V at 120mA for positive rails and -15V at 120mA for negative rails. It also features two charge pumps for gate driver supply, capable of delivering up to 22V and -20V respectively. An adjustable VCOM driver offers precise panel-backplane biasing from 0V to -5.11V with ±1.5% accuracy.

The TPS651851RSLR operates within a temperature range of -10°C to 85°C. It is available in a 48-VFQFN exposed pad package, suitable for surface mount applications. The device supports features such as I2C control, power sequencing, and adjustable soft-start, making it a versatile solution for driving E-Ink displays.
