TPS65190RHDR

The TPS65190RHDR from Texas Instruments is a multi-channel level shifter and VCOM buffer specifically designed for large format LCD display applications, such as TVs and monitors. It effectively converts logic-level signals from the Timing Controller (T-CON) into the high-level gate drive signals required by the display panel.

This IC features 10 level shifter channels organized into two groups, each with separate positive supplies (VGH) and a common negative supply (VGL). The VGH levels can range up to 38V, while VGL levels can go down to -13V. The device also includes a high-speed VCOM buffer, suitable for driving the panel's common rail voltage with high slew rate and peak current capability.

The TPS65190RHDR operates within a temperature range of -40°C to 85°C and is housed in a 28-pin 5x5 mm VQFN package with an exposed pad. It is surface-mount compatible and comes in a standard package quantity of 3,000 units on a large tape and reel.

Key specifications include operating voltages from 12V to 38V, making it suitable for various display power requirements. The function of the device is to act as both a buffer and a shifter for video signals.
