The buck converter uses an inherent switching action to regulate voltage. This switching frequency can affect the performance of a buck converter,and is thus very important. This application report analyzes the influence of switching frequency on buck converter performance in terms of efficiency, thermals, ripple, and transient response. It also shows bench test results at both 600-kHz and 1000-kHz using the TPS568230.
