Texas Instruments TLC6C5748EVM LED Driver Evaluation Module (EVM)

Texas Instruments TLC6C5748EVM LED Driver Evaluation Module (EVM) helps users evaluate the characteristics, operation, and use of the TLC6C5748-Q1. The Texas Instruments TLC6C5748-Q1 is a 48-channel, 16-bit, PWM LED driver with internal current settings mainly designed for automotive local dimming backlight. Each channel has an individually adjustable pulse width modulation (PWM), grayscale (GS) brightness control with 65,536 steps, and 128 steps of constant-current dot correction (DC). DC adjusts brightness deviation between channels. All channels have a 128-step global brightness control (BC). BC adjusts brightness deviation between the R, G, B color groups. The eight-step maximum current-control (MC) selects the maximum output current range for all channels of each color group. GS, DC, BC, and MC data are accessible with a serial interface port.

Features

  • 48 outputs with 7-bit DC for each output
