Description
This reference design showcases a solution using a 48-channel LED driver TLC5957 to drive a 10×16 full color (R/G/B) LED matrix with a 1/10 multiplexing rate. This design enables you to drive 160 RGB LEDs with only one TLC5957 LED driver and five dual PMOSFETs. The design provides selectable PWM grayscale bits from 9-bit to 16-bit, which results in a fine and smooth display effect. Because the TLC5957 LED driver provides 512-step adjustments for each color, it is easy to get a desired white balance. Also, the LED open detection and thermal shutdown functions help to ensure high system reliability.
Features
- 1/10 Multiplexing Ratio
- Pre-Charge FET for Ghosting Reduction
- PWM Grayscale Selectable From 9 bit to 16 bit
- 512-Step Adjustment for Each Color Group
