Abstract:
A voltage regulator includes power stages and a controller. The power stages are configured to provide power to a load in response to a pulse-width modulated (PWM) signal and to provide a body braking to the load in response to a body braking signal. The body braking is provided via a body diode of the power stage. The controller is configured to provide the PWM signals to a first power stage and a second power stage based upon a power demand of the load, to provide body braking signals to the first power stage and the second power stage in response to an over-voltage condition on the load, and to suspend the first body braking signal to the first power stage and maintain the second body braking signal to the second power stage, in response to an over-temperature condition on the first power stage.
