TPS65142RTGR Description

Short technical summary and product information.

The TPS65142RTGR from Texas Instruments is a specialized power management IC designed to provide a compact solution for the bias power and WLED backlight requirements in note-pc TFT-LCD panels. It integrates a boost converter, a positive charge pump regulator, and a negative charge pump regulator to power source and gate drivers.

Key electrical features include a 2.3-V to 6-V input voltage range for bias, a boost converter with an 1.8-A switch current, and selectable switching frequencies of 1.2 MHz or 650 kHz. The device also supports a 4.5-V to 24-V WLED backlight input range and includes a 150-mA unity-gain VCOM buffer. For WLED driving, it offers 6 current-sink channels, each capable of 25 mA, with better than 3% current matching and up to a 1000:1 PWM dimming range.

Designed for improved image quality, the TPS65142RTGR incorporates gate voltage shaping and an LCD discharge function. A reset function ensures proper TCON reset at power on. The IC is housed in a compact 32-pin, 6 mm x 3 mm WQFN package, suitable for surface mounting.

This device is ideal for applications requiring integrated bias and backlight power solutions for LCD panels, such as in notebooks and other portable display devices.
