10 Power Supply Recommendations
TLC59210 operates from a VCC range of 3 V to 5.5 V. The system will also require a power supply for the LEDs.
The supply voltage of the LEDs must be greater than the forward voltage of the LED plus the VOL of the
channel, but not greater than 30V.
11 Layout
11.1 Layout Guidelines
The traces carrying power through the LEDs should be wide enough to handle the necessary current. All LED
current passes through the device and into the ground node. There must be a strong connection between the
device ground and the circuit board ground.
