Product Overview: TPS65185RSLR from Texas Instruments

The TPS65185RSLR is a high-performance power management integrated circuit (PMIC) designed by Texas Instruments specifically for E-Ink® displays. This device is engineered to provide a complete power supply solution for portable and battery-powered applications that utilize electrophoretic displays, such as e-readers, electronic signage, and other low-power display products.

The TPS65185RSLR offers a versatile and efficient design, featuring multiple output voltages that are essential for driving the various segments of an E-Ink display panel. These include positive and negative gate voltages, source and border voltages, as well as a boost converter to supply the positive input voltage for the panel. The integration of these outputs into a single chip simplifies the design process, reduces the overall footprint, and enhances system reliability.

Key features of the TPS65185RSLR include programmable sequence control for power-up and power-down scenarios, which ensures that the voltages are supplied in the correct order and timing for optimal display performance. The device also incorporates a high-efficiency, 1.5-A-capable switch-mode boost converter, a fully integrated 1.5-A negative charge pump, a high-accuracy voltage reference, and a programmable VCOM calibrator to fine-tune the display's common voltage.

Safety and protection are paramount in the design of the TPS65185RSLR. The chip includes under-voltage lockout (UVLO), thermal shutdown, and over-current protection mechanisms. This ensures that the device operates within safe parameters, protecting both the PMIC and the display from potential damage caused by abnormal operating conditions.

The TPS65185RSLR comes in a compact QFN package, making it ideal for space-constrained applications. Its high level of integration and advanced features make it a go-to solution for designers looking to create efficient, reliable, and high-quality E-Ink display systems. With Texas Instruments' reputation for quality and performance, the TPS65185RSLR stands out as an exemplary power management solution for the next generation of electronic paper displays.
