Typical application
6.1
Output current capability and ic power dissipation
In Figure 24 is shown the approximate relation between the output current and the IC power
dissipation using PWM current control.
For a given output current the power dissipated by the IC can be easily evaluated, in order to
establish which package should be used and how large must be the on-board copper
dissipating area to guarantee a safe operating junction temperature (125 °C maximum).
