TLC5930 12-CHANNEL LED DRIVER SLLS528 – MARCH 2002 FEATURES D 0.2-mA to 40-mA (Constant-Current Sink) Drive Capability x 12 Bits Output Count into 24-Pin HTSSOP Package D 1024 Gray-Scale Display (PWM Control 1024 Steps) with Max 25-MHz Clock Frequency D 3-Way Brightness Adjustment – Plane Brightness Adjustment for 64 Steps (40% to 100%) – Frequency Division for 16 Steps (6.3% to 100%) – Dot Correction for 256 Steps (0% to 100%) D DS–Link Data Input/Output (Data Rate Max 20 Mbps) with Packet Operation D 5 Error Information Types and 2 Gray–Scale Clock Modes D 3.3-V VCC and LVTTL Interface APPLICATION D Full- or Multi-Color LED Display DESCRIPTION The TLC5930 is a constant-current sink driver with an adjustable current value, and 1024 gray scale display that uses pulse width control. The output current is 0.2 mA to 40 mA with 12 bits of RGBx4. The maximum current value of the constant-current output can be set by one external resistor. The TLC5930 includes three kinds of brightness adjustment functions: one adjusts the plane brightness between devices, changing the current values of all outputs uniformly. The second adjusts the frequency division to controls overall panel brightness, and the third adjusts the dot correction per LED, changing the current values of independent output. The TLC5930 also includes color–tone correction function for correcting color per dot (pixel) and OVM function for constant-current output terminals used for LED failure detection. Other feature...
