Pulse-Width Modulation Current Control with Reduced Transient Time |
摘要 |
One embodiment of the present invention includes a current regulator circuit. The circuit includes at least one switch configured to periodically couple and decouple a respective at least one voltage rail to an inductor to maintain a current through the inductor. The circuit also includes a pulse-width modulation (PWM) controller configured to set a duty-cycle associated with a switching signal to control the at least one switch based on a feedback signal that is associated with a magnitude of the current. The circuit also includes a switch-controlled current path configured to shunt the current from a load in response to a control signal. The circuit further includes an error circuit configured to provide an error term to the PWM controller upon activating the control signal to adjust the duty-cycle substantially instantaneously in response to the control signal.
