TPS65140 Description

Short technical summary and product information.

The Texas Instruments TPS65140 is a specialized power management IC designed to provide the necessary voltages for thin-film transistor (TFT) LCD displays. It offers a compact power supply solution with three independently adjustable outputs.

 

The main output, VO1, is a boost converter capable of delivering up to 15V at 350mA with less than 1% typical output voltage accuracy. The device also includes a negative regulated charge pump for VO2, providing voltages down to -12V at 20mA, and a positive regulated charge pump for VO3, delivering up to 30V at 20mA. An auxiliary 3.3V linear regulator controller is also integrated.

 

Key features include a 1.6-MHz fixed switching frequency and protection mechanisms such as short-circuit detection, overvoltage protection, and thermal shutdown. The TPS65140 is qualified for automotive applications and is available in a TSSOP-24 PowerPAD package.

 

This IC is suitable for applications such as infotainment systems, automotive displays, instrument clusters, and center consoles where multiple, precisely controlled voltage rails are required for LCD operation.
