ABSTRACT:
A method for providing precise current regulation and limitation for a power supply is provided. The method includes amplifying any difference between a load current signal and a current setting reference signal with a feedback loop amplifier to generate a feedback signal. A power output signal is generated based on the feedback signal. An output signal for the power supply is generated based on the power output signal. The load current signal and the current setting reference signal are generated based on the power output signal. An offset error signal is generated based on the load current signal and the current setting reference signal. A differential bias for the feedback loop amplifier is adjusted based on the offset error signal.
