TPS65148RHBR Description

Short technical summary and product information.

The Texas Instruments TPS65148RHBR is a specialized power management IC designed to provide the necessary LCD bias voltages for Thin Film Transistor (TFT) LCD panels. It operates with an input voltage range of 2.5V to 6V and can generate source driver voltages up to 18V.

Key features include a boost converter with a 4A switch current, selectable switching frequencies of 630kHz or 1.2MHz, and adjustable soft-start. The IC also incorporates a voltage regulator for gamma buffer, gate voltage shaping, a VCOM buffer, a reset generator, and an LCD discharge function. It offers overvoltage and overcurrent protection, along with thermal shutdown for reliability.

This IC is housed in a 32-pin, 5x5mm VQFN package, making it suitable for space-constrained applications. It is ideal for display applications such as monitors and TVs, particularly those running from a typical 5V supply rail.

The TPS65148RHBR is designed for applications requiring precise control over LCD bias voltages, ensuring optimal display performance and image quality.
