As with every power supply design, there are trade-offs to be made, but losing efficiency when using high-switching frequency converters doesn’t necessarily have to be one of them. This application note shows that at higher loads operating at high-switching frequencies can have an efficiency benefit at higher currents, due to the fact that they allow for the use of inductors with a lower inductance and as a result lower DCR.
