Overview of Texas Instruments TPS65100PWPR

The TPS65100PWPR from Texas Instruments is a versatile and efficient power management integrated circuit (PMIC) designed specifically for portable and compact LCD applications. This PMIC is ideal for driving the power supply of a thin-film transistor (TFT) LCD panel, which is commonly used in devices such as notebook computers, tablet PCs, and portable media players.

Key Features

• Multiple Output Voltage Rails: The TPS65100PWPR provides a range of output voltages necessary for LCD operation, including V_POS (positive supply), V_NEG (negative supply), and V_COM (common voltage). These are generated from a single input voltage, simplifying the power supply design.
• High Efficiency: The device includes a high-efficiency step-up converter for the positive supply voltage and a linear regulator for the V_COM buffer.
• Adjustable Outputs: The output voltages are adjustable through external resistive dividers, allowing for precise matching to the requirements of the specific LCD panel being used.
• Thermal Protection: It incorporates thermal shutdown protection to safeguard the device and the system it powers in the event of overheating.
• Small Package Size: The TPS65100PWPR comes in a compact TSSOP (Thin Shrink Small Outline Package) with PowerPAD™, minimizing the footprint on the PCB and making it suitable for space-constrained applications.

Applications

Thanks to its comprehensive feature set and compact size, the TPS65100PWPR is an excellent choice for a wide range of applications that require reliable and efficient power management for LCD panels. Its ability to drive multiple voltage rails with high efficiency makes it a go-to solution for designers working on:

• Notebook computers
• Tablet PCs
• Portable media players
• Other portable devices with TFT LCD screens

Overall, the TPS65100PWPR is a testament to Texas Instruments' commitment to providing innovative power management solutions that meet the evolving needs of modern electronic devices.
