Power Dissipation
temperature, in which the device requires the maximum output current calculated for given
operating conditions. The maximum allowable power consumption can be calculated by the
following equation:
The relationship between power dissipation and operating temperature can be refer to the figure
below:
The power consumption of IC can be determined by the following equation and should be less than
the maximum allowable power dissipation:
8-bit Constant Current LED Driver with Error Detection
The power dissipation of a semiconductor chip is limited to its package and ambient
