TLC6C5912
SLIS180 – MAY 2016
9.2.2 Detailed Design Procedure
To begin the design process, the designer must decide on a few parameters:
• Vsupply: LED supply voltage
• VDx: LED forward voltage
• I: LED current
After determining the parameters, calculate the resistor in series with LED using Equation 1.
Rx = (Vsupply – VDx) / I
