摘要：
A method includes receiving an activation signal at a semiconductor device and generating an output power signal at the semiconductor device in response to receiving the activation signal. The output power signal has a duty cycle. The method also includes providing the output power signal to a load. The output power signal provides power to the load. An amount of power provided to the load is based on the duty cycle of the output power signal. In addition, the method includes adjusting the duty cycle of the output power signal using at least one of a current limiter and a power limiter integrated in the semiconductor device.
