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.
