Patent ID: 7098622

Claim:
A programmable power supply having a voltage control mode and a current control mode and selectively operable in each mode, the programmable power supply comprising: a power mesh which drives a load in response to a first control voltage or a second control voltage; a voltage control loop which generates the first control voltage and provides the first control voltage to the power mesh during the voltage control mode; a current control loop which generates the second control voltage and provides the second control voltage to the power mesh during the current control mode; a first tracking clamp which maintains the first control voltage offset from the second control voltage by a first predetermined value during the current control mode; a second tracking clamp which maintains the second control voltage offset from the first control voltage by a second predetermined value during the voltage control mode; and a dynamic offset injector which senses a mode transition and outputs a third control voltage to the first tracking clamp or the second tracking clamp to alter the first predetermined value or the second predetermined value, respectively, during the mode transition.
