Overview of Texas Instruments TPS65185RSLR

The TPS65185RSLR is a versatile power management integrated circuit (PMIC) designed by Texas Instruments (TI) to cater to the unique needs of E-Ink® displays, which are commonly found in e-readers and electronic shelf labels. This PMIC is engineered to provide a precise and reliable power supply for the various voltage requirements of E-Ink panels, ensuring optimal performance and efficiency.

Key Features

• Multiple Output Voltages: The TPS65185RSLR generates the four necessary supply rails for E-Ink displays: VPOS (positive supply), VNEG (negative supply), VCOM (common supply), and VDDH (high supply voltage). These outputs are programmable via an I2C interface, which allows for easy adjustment and control.
• High-Efficiency: With an integrated high-efficiency boost converter, the device ensures minimal power loss during voltage conversion, which is crucial for battery-powered applications.
• Adjustable Sequencing: The PMIC allows for flexible sequencing of the power-up and power-down of the voltage rails, which is essential for the proper operation of E-Ink displays.
• Thermal Protection: Built-in thermal shutdown protection safeguards the device against overheating, ensuring long-term reliability and safety.
• Fault Protection: The TPS65185RSLR features under-voltage lockout (UVLO), over-voltage protection (OVP), and short-circuit protection, which contribute to the stability and durability of the end application.

Applications

Primarily designed for E-Ink displays, the TPS65185RSLR is ideal for a range of applications such as:

• E-Book Readers
