TPS65146RGER Description

Short technical summary and product information.

The TPS65146RGER from Texas Instruments is a specialized power management IC designed to supply the necessary bias voltages for Thin Film Transistor (TFT) LCD panels. It is suitable for applications in notebook PCs and monitors, particularly for displays ranging from 13 to 21 inches.

This IC integrates a step-up converter for V S (Source Driver voltage), capable of reaching up to 16.5V with a 2A switch current. It also includes a positive charge pump regulator for V GH (Gate Driver High voltage), a logic voltage rail provided by an integrated 500mA LDO, and a Vcom buffer for driving the LCD backplane. Additional features include gate voltage shaping, output discharge, a reset generator, overvoltage protection, thermal shutdown, and undervoltage lockout.

The TPS65146RGER operates within a 2.5V to 6.0V input voltage range and has an operating temperature range of -40°C to 85°C. It is housed in a compact 24-pin VQFN (4mm x 4mm) package, making it ideal for space-constrained designs. The selectable switching frequency of 650kHz or 1.2MHz offers flexibility in design.

This device offers a very compact power supply solution for LCD bias requirements, simplifying the design of portable electronics and displays. Its integrated functions reduce component count and board space.
