External adjustment of a drive control of a switch

A control system coupled to control a transistor which is coupled to control energy delivery to a load, comprising:

• a system controller coupled to sense an event in the control system and to assert a command signal in response to the sensed event;
• an interface coupled to the system controller to receive the command signal, wherein the interface is coupled to interpret the command signal and output a drive characteristic signal;
• and
• a first switch controller coupled to receive the drive characteristic signal from the interface, the first switch controller further coupled to control the turn on and the turn off of the transistor to control the energy delivery to the load, wherein the first switch controller is further coupled to control the turn on or the turn off, or control both the turn on and the turn off, of the transistor with a first drive strength or a second drive strength in response to the drive characteristic signal representing a first command or a second command of the command signal, wherein the switch controller is coupled to adjust the rise time or the fall time, or adjust both the rise time and the fall time, of a current conducted by the transistor.
