* Main LED power uses one pin to turn the Opamp on/off,
* and one pin to control Opamp power level.
+ * Linear brightness control uses the power level pin, with dynamic PWM.
* The on/off pin is only used to turn the main LED on and off,
* not to change brightness.
* Some models also have a direct-drive FET for turbo.
