16-Bit Constant Current LED Drivers
Note
temperature, this device requires a maximum output current given by an operating condition.
The maximum allowable power consumption (Pd (max)) of this device is calculated as
follows:
Based on the Pd (max), the maximum allowable current can be calculated as follows:
Pd
