TLC5958 Description
The TLC5958 is a 48 channels constant-current sink driver for multiplexing system with 1 to 32 duty ratio. Each channel has an individually-adjustable, 65536step, pulse width modulation (PWM) grayscale (GS). 48K bit display memory is implemented to increase the visual refresh rate and to decrease the GS data writing frequency.
