Apparatus and method for two tier output stage for switching devices

A circuit for reducing EMI is provided. The circuit includes driver circuitry that drives a power switch, such as a power MOSFET. The power switch provides an output voltage. The circuit decreases the drive strength by which the power switch is driven during each output edge (i.e. when the output goes from low to high (rising edge) or high to low (falling edge)), and returns the drive strength to its normal level when the output edge is complete or approximately complete. Reducing the drive strength of the driver circuitry causes the output edge to occur over a longer period of time. This results in reduction of the EMI of the device.
