ABSTRACT:
A power device controller includes a voltage mode control loop to generate an error voltage and to control a power device and a current mode control loop to generate a current control voltage and to control the power device. The current mode control loop includes a current feed-forward to reduce a load dependence of a loop gain by reducing a load current dependence of a low frequency component of a gain of the error voltage to the output voltage with a current loop closed. A multi-phase power device controller for controlling several power devices includes a shared voltage mode control loop to generate an error voltage and a shared current mode control loop to generate a current control voltage, the shared current mode control loop including a current feed-forward to reduce a load current dependence of a low frequency component of a loop gain.
