Abstract
An apparatus and method for limiting the output current in a switched mode amplifier are implemented. The apparatus includes a driver amplifier configurable for selective operation in one of three modes. The amplifier is operable for transitioning between the first mode and one of the second and third modes in response to a state of an output node of the driver. Bias circuitry, configurable for selective coupling to the driver amplifier is operable for limiting the output current of the amplifier in the first operating mode.
